Welcome to NonBleedingEdge!


Geoffrey Collis

This site is an online collection of my cheatsheets and howtos.

I admit the name NonBleedingEdge is kind of strange, but resulted from a discussion with another aging techie who also found himself forced into semi-retirement…


How can an *aging techie* be of any use in the ever changing I.T. industry?


Your brain stops functioning at 50… right? 🙄


“Experience” which should never be under-valued. 💡

This site is written by an aging techie so obviously is Non-Bleeding-Edge! 😆

  • It attempts to condense various work experience into quick reference guides.

  • The style is deliberately terse, like an engineering logbook.

  • Suggestions, comments, corrections or contributions are always welcomed.
