XSendfile: critical for Rails 3.1 on Apache
After several hours troubleshooting my production Rails environment, I finally found out why images were not being served properly after an upgrade to 3.1: no XSendfile module.  Rails 3.1/Sprockets apparently relies heavily on Apache’s XSendfile to serve assets, and without the module installed and configured, images will silently fail and browsers will display a missing image.

When using Heroku, Postgres is a Must
Why does my application work in the local development environment, but not in production? Heroku is an awesome service.  It provides a stable platform and tools for quickly deploying applications to the cloud, and allows users to enjoy all the scaling benefits cloud infrastructure can provide.  One gotcha I have experienced, however, is Heroku’s reliance on the Postgres database, instead...

WatchWatch
The oil continues to flow, and it does not bode well for life in the Gulf.  Based on studies at UNC of the Exxon Valdez in 2003, “…environmental consequences of the Exxon Valdez oil spill went far beyond the more than 250,000 seabirds, thousands of marine mammals and countless numbers of other coastal marine organisms killed in the first days, weeks and months.”

My Hosting Rails account has long been neglected.  Because of that I’m moving to tumblr, because: It’s more fun. I don’t have to maintain it. I hope to post more regularly in the future, thanks for stopping by!
