| * Update: 2013-11-13 - Picked up another technique thanks to reading this post from Tyler Tate, auto-fill in the second filename for the retina image, http://tylertate.com/blog/2013/06/11/retina-images-using-media-queries-and-LESS-CSS.html | |

Ordering a query result set by an arbitrary list in PostgreSQL
I'm hunting for the best solution on how to handle keeping large sets of DB records "sorted" in a performant manner.
Most of us have work on projects at some point where we have needed to have ordered lists of objects. Whether it be a to-do list sorted by priority, or a list of documents that a user can sort in whatever order they want.
A traditional approach for this on a Rails project is to use something like the acts_as_list gem, or something similar. These systems typically add some sort of "postion" or "sort order" column to each record, which is then used when querying out the records in a traditional order by position SQL query.
This approach seems to work fine for smaller datasets, but can be hard to manage on large data sets with hundreds (or thousands) of records needing to be sorted. Changing the sort position of even a single object will require updating every single record in the database that is in the same sort group. This requires potentially thousands of wri

Git hook that determines the author based on the email address in a SSH key. Doesn't work because Git doesn't check the config between pre-commit and commit.

Capistrano automates pushing out a new version of your application to a deployment location.
I've been writing and deploying Rails apps for a while, but I avoided using Capistrano until recently. I've got a pretty simple one-host deployment, and even though everyone said Capistrano was great, every time I tried to get started I just got snowed under not being able to figure out exactly what I wanted to do, and figured I wasn't having that much trouble doing it "manually".
