Mark Berry November 27, 2012

I recently transitioned from SBS 2008 to a clean install of Server 2012 Essentials. Most things went smoothly, but one issue took a lot of work to resolve:  on an XP development machine, I could read from but not write to the SQL 2000 server running on Server 2003.

Convert a Select Drop-Down Box to an Autocomplete in Rails

Mark Berry October 30, 2012

I created a nice select drop-down box in Ruby on Rails 3.2.8 using SimpleForm 2.0.2 and Twitter Bootstrap 2.0.3, with authentication from CanCan 1.6.8.

Here is my current approach for formatting time zone and date/time values. I’m using Rails 3.1.3, SimpleForm 2.0.1, and Twitter Bootstrap 2.0.1. I had some trouble finding examples of how to do this so maybe this will help someone.

Install Rails 3.1 for the Rails Tutorial

Mark Berry September 27, 2011

I’ve been working through Michael Hartl’s Ruby on Rails Tutorial. I had some trouble in chapter 13 installing the released version of Rails 3.1.0, so I thought I would post what worked for me.
