[...] I was able to solve my performance issue by tuning ruby’s garbage collection settings. It only takes a few minutes to setup, but then you’ll have to tweak the settings to your app to get the best results. The details for how to put the GC settings in place are explained very well in this post. [...]

I can indeed. In the meantime, you can install it directly with an APK if you’d like; http://dl.dropbox.com/u/6857506/FlexAuth.apk should be the latest (and that’s my dropbox, so I guarantee the file’s authenticity).

It seems incompatible with Android 2.3.4, since it doesn’t show up in the market on my phone anymore. Could you check this out?

Comment on MongoDB: Warts and wobbles by Chris Heald

Yeah, definitely. For small simple aggregations, group() works, but if you have a lot of data, it doesn’t work due to the 10k key limit. This is one area in which SQL is clearly superior, because it’s really the core strength of those sorts of databases.

the mongo group command might be a bit more compact to write than map/reduce for a simple aggregation. however it is not as powerful and has some restrictions.

work is underway on improved aggregation functionality — agree it can be better.

FWIW, i consider this something that sql is very good at — the GROUP BY operator is a very compact way to represent this sort of concept.

Comment on Tarot for easier Rails configurations by Chris Heald

This is very similar to what Tarot actually does. As far as gems go, it’s really small, but it’s so commonly reused that it’s nice to be able to just drop it into a Gemfile and go.
