Rails and Scaling with Multiple Databases. Ryan Tomayko explains how his team spreads a high traffic Rails application across five separate PostgreSQL databases by giving each client their own schema—similar to how WordPress MU scales.

XSS. Sanitising HTML is an extremely hard problem. The sanitize helper that ships with Rails is completely broken; Jacques Distler provides a better alternative.

The No-Shit Guide To Supporting OpenID In Your Applications. Fantastically useful: Dan Webb digs through the API documentation so you don’t have to. The example code is for Rails but the PHP and Python libraries work in much the same way.

OpenID makes web identities real and appealing. DHH has caught the OpenID bug. Expect to see a flurry of activity around OpenID in the Rails community over the next few weeks.

Rails 1.2.1 Impression. I hadn’t seen assert_select before, which lets you unit test generated HTML using CSS selectors; a really neat idea.

A brief update with some numbers for hardware load-balanced mongrels. 4000 requests/second on 48 mongrels behind a hardware load balancer.

Rails vs Django Paper and Slides. Even if you’ve already read the paper you should check out the slides. Really good flow, clear and clever use of diagrams.

Django on Dreamhost: incomplete headers. Fix this problem on Dreamhost by renaming django.fcgi to dispatch.fcgi (they special-case for Rails users; Django users can tag along).

Release: Unobtrusive Javascript For Rails 0.2. RJS kind of sucks. This looks like it doesn’t.

On the total nondisclosure of the 8/9/06 [Rails] security vulnerability. The best argument I’ve seen in favour of full disclosure.

A Week in Chicago with Rails, Perl, and Django. I love Nat’s observations about Java programmers who discover dynamic languages.

Reuse-in-the-large is an unsolved problem: Why I left OpenACS for Rails. Fascinating insight in to the reason frameworks that do less do more.

Rails is the devil on your (client-side) shoulder. This is exactly why I’m not a fan of RJS.
