1. Improve ColdFusion performance by 1000x?
I recently had to deal with some ColdFusion page optimization. Although the result was not 1000 better like in this case, the approach was more or less similar. Instead of SQL indexes + rewriting queries inside loops + caching queries, I only had to do a combination of:
– reducing the number of DB queries by moving them outside loops
cfqueryparam. In addition to making things more secure, turns out it also has a significant impact on performance tuning.
2. About helping others
Apparently helping others is embedded in every human’s DNA. Here’s an excerpt (no spoilers) from Andy Meir’s ‘The Martian’ – one of the best SF novels I ever read:
Every human being has a basic instinct to help each other out. It might not seem that way sometimes, but it’s true. […] This is so fundamentally human that it’s found in every culture without exception. Yes, there are assholes who just don’t care, buy they’re massively outnumbered by the people who do.
– The Martian (coming in a theater near you in 2015)
The downside of this ‘feature’ of the human behavior is that it can be exploited. For example, in computer security, individuals who are attempting to social engineer some piece of information strongly rely on this aspect of the human nature:
Don’t rely on network safeguards and firewalls to protect your information. Look to your most vulnerable spot. You’ll usually find that vulnerability lies in your people. […]
Most people generally want to help somebody who is requesting help.

3. The Rosie Project
The Rosie project is an amazingly enjoyable book about a socially-challenged scientist who is working his way through the process of finding a life partner. Also recommended by Bill Gates. If anyone makes a movie out of it, I hope they pick Jim Parsons for the main role
