Lament about IT and Communication of Knowledge

Like a lot of people who work with computers, I have some communication problems. Sometimes, I'm too blunt; other times, too reticent.

Postfix Install Stuff

(argh, forgot to back up my postfix work. i have to start fresh, so this is an opportunity to document work.)

Install Java JDK into /usr/local/bin

There's a zillion ways to do it, and editing $PATH is probably the best, but I didn't want to do that, so I did this:

Limited Email

I've been working on learning postfix and migrating email accounts to it. The service I'm dreaming about is going to be "limited email" and differs entirely from the big email servers.
