Caffeine is essential for keeping the brain active during nightly hacking sessions. There are, however, many ways to satisfy a hacker's need for caffeine. Drinking Canned Capitalism (Coke) contradicts the very principles of the open source movement, for it is a closed source product, manufactured by a huge, evil corporation. This sweet brown fizzy water is unhealthy and does not leave any space for creativity; you just get what you pay for. It is like M$ Windoze. Coffee is somewhat better (much better, in fact), though it can cause irreversible neural damage especially in young hackers still in larval stage (e.g. K-8), if consumed in large quantities. Moreover, it is strongly addictive and does not taste very good for those not yet addicted. A good tea, however, induces catharctic sensations even in those, who drink it for the very first time, warming one's mind, body, and soul. Many cultures have developed excellent ways of producing delicious tea. The English, the Chinese, the Japanese and many more have mastered the art of this divine beverage. In this HOWTO, however, I would like to focus on my native, Russian way of preparing, serving and consuming tea. The issues of scalability (preparing tea for yourself versus the LUG gathering), portability (preparing tea using different utensils), and quality control are also addressed in this HOWTO. Cultural references are given for the curious. Enjoy!
