2 Linux Tips

  1. Use ntpdate to synchronize linux server with a public ntp server

    Do it automatically within crontab:
    0 3,9,15,21 * * * /usr/sbin/ntpdate -u time.nist.gov | logger -t NTP

  2. Change the default editor in Ubuntu to VIM

    sudo update-alternatives --config editor
    Select VIM and say farewell to Nano.

Greek Alphabet

Ah, the Greek Alphabet. I just hate it when a book uses a symbol from the Greek alphabet, yet forgets to teach the reader how to pronounce the symbol. So here it is the Greek alphabet and English equivalent pronunciation:

(One may argue that any book that uses the Greek Alphabet is absolutely boring and I would have to agree.)

alpha, beta, gamma, delta, epsilon, zeta, eta, theta, iota, kappa, lambda, mu, nu, xi, omicron, pi, rho, sigma, tau, upsilon, phi, chi, psi, and omega.
