New Relic has what looks like a really nice tool for monitoring Rails applications. It’s called RPM and it looks to give some really good insight into where performance bottlenecks occur in a Rails app.

37signals reported some excellent results after a round of performance tuning based on their findings from RPM.

Your mileage may vary. But RPM looks to be one of a very small number (perhaps the number 1) of tools that can help in this way with performance analysis, which is the first step to performance improvement.

Definitely worth a look if you’re doing any Rails development.

There is an excellent screencast tutorial on .NET MVC available for anyone interested in web-development with asp.net. The MVC screencasts are at the bottom of the page

I think this collection of screencasts will be particularly helpful to anyone coming to .NET from Ruby on Rails or other strongly MVC paradigms. .NET can be a bit overwhelming at first, without a solid entry point/introduction to the framework. These tutorials should help you get started on the right foot.

Look forward to seeing the results.
