We recently came across a situation in our markup where we wanted whitespace in the markup for readability, but we didn't want that whitespace represented between the elements.
We found a fix that suggested using font-size: 0 in CSS to eliminate the whitespace. That worked fine in Chrome, but we found that in Firefox, the containing element no longer scrolled with the mouse wheel or arrow keys! Apparently Firefox's scroll speed is proportional to font-size.

How to scrub production data
- try my_obfuscate
- use handcrafted update-all sql
Interesting Things
- Do not stretch monitor cables, they make the ports break
- MySql: Different os have different rules on table case sensitivity(My_Table <-> my_table), be strict or you get into trouble
- validates_acceptance_of can crash your asest:precompile on heroku (because it uses the db when loaded, but db is not yet ready), least hacky solution: validates_acceptance_of xxx unless ENV['RAILS_ASSETS_PRECOMPILE']

"When using the wkhtmltopdf library via the PDFKit gem, if you use an HTML snippet that does not have a height defined, it generates a PDF that appears to only be an image, the text is not searchable or selectable. If you give your element a height however, it behaves as you would expect. Both PDF documents visually look the same though."

Our team ran into an issue installing Ruby 1.9.3 on Lion today. When running...
$ rvm install ruby-1.9.3
... the installer fails with an error message including "checking whether the C compiler works... no" even though we had XCode and gcc installed.
After some reading on StackOverflow and Github I found this solution [1]...
$ rvm install 1.9.3-p0 --with-gcc=clang
... which points an explanation on RVM's issue tracker [2].

"git checkout -" will toggle you between your last two checkouts (branches or just plain SHA's). Handy if you are switching back and forth. Can't seem to find it mentioned anywhere in the docs though.
