I’ve written several things about the Linux cron command and crontab file format before, and as a quick note, here’s some information on the format of the crontab date and time fields.

Scala number, date, and formatting examples

This short blog post contains a collection of Scala number and date examples. I created most of these in the process of writing the Scala Cookbook.

Zen Master Seung Sahn

One of the most valuable lessons I learned when I created Mission Data was to hire well. Phrases like this have become more popular recently when people learned of the Steve Jobs quote, “A players hire A players, and B players hire C players,” and other similar quotes. Guy Kawasaki, who was there during the early Apple days, expanded on this quote with his own thoughts:
