This weekend was spectacular. I went for a bike ride for the first time since grant deadlines began in August and took some hills without any trouble, following some pointers from Andrew. I enjoyed the exercise and the fantastic weather.

Somewhere in your childhood is a gaping hole. Fill this hole.

Remember to take some time away from campus — from the demands of schoolwork and the trappings of the college social life.

• Every new technology will bite back. The more powerful its gifts, the more powerfully it can be abused. Look for its costs.

• Technologies improve so fast you should postpone getting anything you need until the last second. Get comfortable with the fact that anything you buy is already obsolete.

• Before you can master a device, program or invention, it will be superseded; you will always be a beginner. Get good at it.

• Be suspicious of any technology that requires walls. If you can fix it, modify it or hack it yourself, that is a good sign.

• The proper response to a stupid technology is to make a better one, just as the proper response to a stupid idea is not to outlaw it but to replace it with a better idea.

• Every technology is biased by its embedded defaults: what does it assume?

• Nobody has any idea of what a new invention will really be good for. The crucial question is, what happens when everyone has one?

• The older the technology, the more likely it will continue to be useful.

• Find the minimum amount of technology that will maximize your options.
