A free mapping service is a wonderful thing, but you might not find all the information you need in OpenStreetMap’s standard view. A number of other free mapping projects extend and enhance OpenStreetMap data to add new features and services. This month, we tour some useful mapping tools based on OpenStreetMap.

Other highlights include:

  • Kernel Disposal – Nuke those old kernels taking up space on your hard drive.
  • Out of Memory Killer – This important component keeps the kernel from running out of memory – but is there a better way?

Check out MakerSpace for a lesson in wearables, and read on to LinuxVoice for a report on the dark market for security exploits.
