Ian is looking for people will experience using the "Koloa Gem". JT recommended to use the standard facebook widgets instead.

In SQL, how do you make a query the opposite of:

where(:name => nil) without using a magic SQL string.

Interesting Things

In SQL null is neither true or false. Be careful for searching for something when a column can have 3 states: true, false and nil. Because falsey comparisons will not work as expected. (RVA, NM)

".DS_Store not disappearing from git even though ignored and removed?"

A developer had some .DS_Store files accidentally checked into a project. It was added to the .gitignore and git rm'd out of the project but they seem to keep showing up as untracked files. Any ideas?

Todd P asks,

How do you properly render a string containing UTF-8 characters across all views?


  • Todd P answers his own help question this morning:

This is with a MySQL database. When you're displaying UTF-8 data, the error you get is:

"incompatible character encodings: ASCII-8 BIT and UTF-8"

I added the following to config/environment.rb:

Encoding.default_external = Encoding::UTF_8 Encoding.default_internal = Encoding::UTF_8

And switched from the mysql gem to mysql2 (0.2.7). Also, make sure to update the adapter in config/database.yml.

"When adding "use strict" into a java script function, JSlint activates strict mode for all javascript."

How do we make "use strict" apply to just one function?
