Hi,

I had been busy with my exams (which got finished today). I'll come up with
more detailed working plan and doubts in a couple of days.

Till now, I have not done much. I had started exploring the code for
optimizer but stopped mid-way and started to read the book "Inside the SQL
Server Query Optimizer" for a better understanding of how the optimizer
works.

I see you're often present on irc, which is great.

I had started exploring tmptable_create_cost.
In sql/sql_const.h: HEAP_TEMPTABLE_CREATE_COST is defined to be 2.0 and
DISK_TEMPTABLE_CREATE_COST as 40.0. As discussed on irc with serg, I'll
start to profile this constant (which I have not started yet).

Blog updates should be fine.
