[LRUG] Talk topics

[Stanisław Klajn]

Hi all!

I am thinking about preparing a talk for some future LRUG meeting, I was
wondering whether you could help me with picking the subject? So far I have
three proposals:

1. Ruby constants - might seem very basic, but there are some common
misunderstanding regarding relations between constants, classes and
modules. It would also cover constant lookup process and rails auto-loading
feature (which is very often a cause of from-time-to-time bugs).

2. ActiveRecord for speed - common and less common ways of dealing with N+1
problem. Topic quite basic, however from my experience it is quite a common
problem.

3. Polymorphic association - basic concept and common problems with an
introduction to gem I'm working on to make polymorphic associations easier
to work with.

Please let me know what you think.

Chers
Stan
