  • Why would you use data structures (ie Binary Trees, Linked Lists) in your jobs/side projects? [closed]

    - by Chris2021
    It seems to me that, for everyday use, more primitive data structures like arrays get the job done just as well as a binary tree would.

  • lead capture apps

    - by Steve

Is there a free software program that I can install on my Ubuntu server to give me secure shell access via a web-interface? I would prefer a small and light-weight solution, so that I can do at least a rudimentary audit of the source code.
