Weary of waiting for a login window? Your driver-drenched Linux distro was configured for all systems, not for your system. This month we show you how to optimize your system for faster startup. Also inside:

  • Battery Time – Get more hours out of your laptop battery with auto-cpufreq and automated frequency scaling.
  • Dstask – this handy personal tracker uses Git version control to store tasks, letting you synchronize your to-do list across multiple devices.

Check out MakerSpace for a look at home telephony on the Raspberry Pi, and turn to Linux Voice for a story on the little-remembered XENIX, a once-popular Unix variant that was maintained and developed by Microsoft.
