Lightning Talks are next week, but no talks have been submitted yet. Unless talks are submitted, it's going to be a long hour of staring at the wall.

- Rails Validates uniqueness allows nils. The database (psql and mysql) allows unlimited nils. *BUG - The app did not allow unlimited nulls. *Cause - The development structure had an allow nil false but the model file had allow nil true. This caused odd behaviour.

"Using Copycopter + WebMock blows up in db:test:prepare"
Try limiting WebMock to load only in the 'test' bundler group.
Interesting Things
- Chrome 15 now shows pseudo selectors in the inspector (Firebug does this as well)
- Automatic semicolon insertion in javascript + Rails 3.1 asset pipeline = hard to debug errors. Be careful with Javascript concatination. USE JSLINT!
- Using Rails 3.1 on Heroku with tinymce-rails fails slug compilation unless you upgrade to the latest version of tinymce-rails.

"License Finder doesn't work with rails 2.3?"
This problem has come up a few times, but no one could recall what the solution was. Might be something about a rake task....
Interesting Things
- MySQL Prefpane isn't working with the Pivotal install on Lion. Seems like it expects a particular installation/configuration. Got around this by reinstalling MySQL from dmg. Another pivot suggested this could be a path issue that could be solved without a full reinstall.
- An older version of Chrome on Windows has a bug with mouse-enter and mouse-leave events. It will think you have left a div if you mouse over a text input contained within that div. Upgrading Chrome should fix this.
- event.layerX and event.layerY will be deprecated at some point... you'll see these warnings now on the newest build of Chrome since it auto-updates.

replaceState() vs pushState() replaceState() can be used for javascript applications instead of pushState() to change the address bar when you don't want to add new items to the browser history.

"accepts_nested_attributes_for doesn't validate nested records? When a form contains two of the same nested attributes and the values of these should cause a validation error (e.g., both have the same email, which has a uniqueness constraint), the form saves properly, but the nested objects are invalid when accessed later."
accepts_nested_attributes_for only validates against the database, but the records in this example would only be in memory. The best solution is to handroll a validator on the parent that iterates over the nested attributes and checks the constraints.
"A Pivot was getting some errors using minified jQuery in IE8, which went away when he used the un-minified version. Any other IE8/jQuery gotchas?"
A few have been mentioned at standup in the past few weeks, most notably some versions of jQuery crash IE8 entirely.
"Is there a way to generate a png from html server-side?"
You can use a command-line tool like webkit2png or there is some rack middleware that can generate pdfs and maybe pngs from html
"A pivot had a page that was requesting images after the page loaded, but couldn't find where they were coming from..."
You can check the originator column of assets in firebug or the chrome developer panel. You can also try overriding jquery ajax to see each call (which you may not want to do if you have a lot of ajax calls).

"Why does RSpec complain that calling .configure multiple times will be deprecated in RSpec 3?"
You shouldn't be calling .configure multiple times.

"Capybara needs to be monkey patched to be able to local a local file:// url in Selenium mode"
Added a method named visit_local which calls into the driver and forces a change to a local URL so no Rack server is needed to serve a static HTML page. A more expansive explanation will be provided in an upcoming blog post.
