Python command line apps

There are a number of Python libraries and modules to help build a command line app from parsing arguments and options to testing to full blown CLI frameworks which handle things like colorized output, progress bars, sending email or pluggable modules.

Python decorators with arguments

The return value of the decorator function must be a function used to wrap the function to be decorated. That is, Python will take the returned function and call it at decoration time, passing the function to be decorated.

Index columns for LIKE in PostgreSQL

Postgres uses trigrams to break down strings into smaller chunks and index them efficiently. The pg_trgm module supports GIST or GIN indexes and as of Postgres version 9.1 these indexes support LIKE/ILIKE queries.

I need to test if gin_trgm_ops is faster than varchar_pattern_ops.

Source making!

Design patterns can speed up the development process by providing tested, proven development paradigms.

The beauty of programming

You can do something the brute force way, the stupid way, or you can find the right approach and suddenly the problem just goes away. You look at the problem another way, and you have this epiphany: it was only a problem because you were looking at it the wrong way.

Less is more. Design the code, design everything.
