Version Control. SSH tricks. Why SSH? As recently as a 2001, it was not uncommon to log in to a remote Unix system using telnet. Telnet is just above netcat in protocol sophistication, which means that passwords were sent in the clear. As wifi proliferated, telnet went from security nuissance to security disaster. As an undergrad, I remember running ethereal (now wireshark) in the school commons area, snagging about a dozen root passwords in an hour. SSH, which encrypts and authenticates connections, had been in development since 1995, but it seemed to become adopted nearly universally and almost overnight around 2002. It is worth configuring SSH properly: per-user configuration is in ~/.ssh/config; system-wide client configuration is in /etc/ssh/ssh_config. Key-based, passwordless authentication Key-based passwordless authentication makes it less cumbersome for other programs and scripts to piggyback atop SSH, since you won't have to re-enter your password each time.
To set this up, first log in to the client machine.

Computer Networking. Elliott Wave Principle. The Elliott wave principle is a form of technical analysis that some traders use to analyze financial market cycles and forecast market trends by identifying extremes in investor psychology, highs and lows in prices, and other collective factors. Ralph Nelson Elliott (1871–1948), a professional accountant, discovered the underlying social principles and developed the analytical tools in the 1930s. He proposed that market prices unfold in specific patterns, which practitioners today call Elliott waves, or simply waves.
Elliott published his theory of market behavior in the book The Wave Principle in 1938, summarized it in a series of articles in Financial World magazine in 1939, and covered it most comprehensively in his final major work, Nature’s Laws: The Secret of the Universe in 1946.
