Making Bookmarklets

I'm feeling very clever. I've got this sweet line of javascript that replaces "cloud" with "butt". My mom would LOVE this, but she doesn't computer very well. I'm afraid to show her the Developer Console and have her type/paste this in. But she IS pretty good at bookmarks, she knows just how to click those!

A bookmark normally takes you to a new web page. A bookmarklet is a bookmark that runs javascript on the current page instead of taking you to a new page. To declare that it is a bookmarklet, the "location" it points to starts with javascript:.

Introduction

Here is a collection of tips and tricks I've picked up about doing performance analysis on Node. Included is a build script that should get a base install of Ubuntu fully functional and ready for all the things we'll be going through.

The script pulls a lot of code from the latest master of each repository. So it's possible that something may fail, but to date I haven't had any issues.

First, go ahead and run the script. Then go take a nice long break. It'll

The prep-script.sh will setup the latest Node and install the latest perf version on your Linux box.

When you want to generate the flame graph, run the following (folder locations taken from install script):

sudo sysctl kernel.kptr_restrict=0
# May also have to do the following:

Documentation-Driven Development

The philosophy behind Documentation-Driven Development is a simple: from the perspective of a user, if a feature is not documented, then it doesn't exist, and if a feature is documented incorrectly, then it's broken.

• Document the feature first. Figure out how you're going to describe the feature to users; if it's not documented, it doesn't exist. Documentation is the best way to define a feature in a user's eyes.
• Whenever possible, documentation should be reviewed by users (community or Spark Elite) before any development begins.
• Once documentation has been written, development should commence, and test-driven development is preferred.
• Unit tests should be written that test the features as described by the documentation. If the functionality ever comes out of alignment with the documentation, tests should fail.
• When a feature is being modified, it should be modified documentation-first.
• When documentation is modified, so should be the tests.
