This is my geek blog. I am Nick Bair, a Linux user striving for proficiency in all areas of computing–setup and administration, networking, programming, security, and so on.
I use this blog to share things of interest with other Linux users. When I learn something new or do something noteworthy, I often find myself thinking, “I should write that down for next time.” The rationale for this blog is that I can write those things down in a place where they’ll not only be there for me next time, but also for everybody else who might need them.

psnup use case will be there for them when they need it–via a web search. And it will be there for me the next time I need it.

So, then, if the device node
/dev/blog were to actually exist, it would point to a weblog, and one could view its contents by typing
cat /dev/blog at the command prompt (
