Information Technology Dark Side

Everything’s a nail In the past I’ve used a jquery plugin for generating links to add events to a calendar, but it recently broke when I upgraded jquery on TroopTrack. So I started banging around trying to get it to work for about an hour before I realized I was being stupid. The jquery library [...]

Not Invented Here I swiped this idea from the work Craig Ulliott did on bodyshopbids.com. Thanks Craig! Don’t hard-code selectors for action and controller specific CSS and Javascript Sometimes you need a bit of CSS or javascript that only applies to a specific action, or maybe to every action on a controller.

Carets and Icons There’s nothing particularly brilliant about these, and they are probably only moderately useful. Mostly I’m putting them out there so that you can (preferably nicely) tell me how stupid I am if there is a better way. Sometimes I will add options to control whether the caret goes after the string or [...]

Problem #1: A nagging memory problem TroopTrack memory gets out of control every couple of days. It bumps up to 95% of available memory and stays there, triggering notifications from New Relic and slowing down traffic as TroopTrack uses swap.

I recently upgraded TroopTrack from Twitter Bootstrap 1 to 2, redesigning a few key aspects of the site to make it more usable. Overall, I was very pleased with the results except for one area – the calendar. I was using a calendar gem that provided a view helper that generates a table based calendar. [...]

I created a form with a hidden field called ‘page’ in my div where I want infinite scrolling to happen. Then I set up my controller action for the action in the normal way with pagination by kaminari: def campaign @testimonials = Testimonial.page(params[:page]) respond_to do |format| format.js format.html end end In campaign.js.erb I simply append [...]
