Random Thoughts on Various Topics
I'm Bob, I have this site on a broad mix of topics including
travel,
Linux and other open-source projects,
cybersecurity,
and
networking,
plus an entire other website containing
oddly specialized travel pictures and commentary.
This collection of essays or musings or rants or what-not
will include content related to those topics,
and content without an obvious home on either site.
Cybersecurity certifications require annual
"continuing education" or
"contributions to the industry",
and a "professional blog" counts.
Blame the greedy companies selling certifications,
because they impose these requirements
hoping that you will pay them for
annual training courses.
