The best title had to be When to Tell Your Kids About Client Caching. Parents might identify more with this. Interesting stuff in any case.

Ruby performance work
Railsconf had several performance-related talks. This one went over a lot of interesting territory.
- Who knew the Date class performed so badly?? Use equivalent ops in Time or get date::performance
- Use String::<< instead of String::+=
- Tune your custom sql with virtual attributes
It’s surprising that things we might not think are performance issues are problematic in ruby. One reason to optimize after you gather metrics that identify problem areas.

During his talk at railsconf, Gregg Pollack showed off Jetbrains Rubymine, an awesome IDE for ruby & rails. I wouldn’t be surprised to find out Jetbrains had a spike in their downloads coinciding with the talk. It is a nice IDE. I was happy to see it includes git support out of the box (I only had to set the path to the git executable). I like the web preview for rails applications. On the downside, I had difficulty opening a large project. I had to stick to more typical rails applications.
It might be time for me to try eclipse again and see how RDT stacks up now.
Contact your usergroup and you can get a deal with Jetbrains to get discounts if you go that route.
