What?

This is a starting point to get something similar to memprof running in ruby 1.9. So far it adds DTrace probes to ruby 1.9.3, which we output and parse at some point later.

This will generate 2 types of probes so far:

• RUBY_OBJ_NEW(): capture the file, line and type of a newly allocated object.
• RUBY_CALL(): capture the function name of every function called. 😱

Partly inspired by this blog post: http://tenderlovemaking.com/2011/06/29/i-want-dtrace-probes-in-ruby.html

When JSLint hurts your feelings, hug it out with Doug.

0. There are some situations that are difficult to distinguish mechanically, so I now consider all of those cases problematic, even when they are not obviously wrong.
1. You should be coding for readability and error resistance.
2. The place to express yourself in programming is in the quality of your ideas, and the efficiency of execution. The role of style is the same as in literature. A great writer doesn't express himself by putting the spaces before his commas instead of after, or by putting extra spaces inside his parentheses.
3. Many people think they have good reasons for doing things badly.
4. [The purpose of JSLint is not to make you feel good about inadequate coding standards.](http://tech.groups.y

-- install FastScripts http://www.red-sweater.com/fastscripts/ and place this AppleScript in the Scripts applications folder for Google Chrome. 
-- For me that was ~/Library/Scripts/Applications/Safari
