Learnings for Week 31 2010

Here’s my learnings from a couple weeks ago.

• jQAPI - alternate location for JQuery documentation. Also provides offline versions you can download as HMTL or an Adobe Air application.

• Homebrew is a package manager for OS X. Packages are defined by formulas that are simple Ruby scripts which is stored in Git underneath.

• Older browsers do not have a native JSON parser but this can be patched with a little bit of javascript from json.org. We ran into this when working with WireIt which does include the Yahoo JSON parser, but doesn’t actually use it everywhere. Adding in the version from json.org works as a stopgap before digging through all of WireIt.

• Ran into an issue calling to_json on a an object that has a carrierwave attachment and have commented on an issue for it. I am running Rails3 RC2 and using FileSystem storage. To get around this I’m simply excluding the file attachment from the to_json:

recipe.to_json(:except=>:photo)
