one of many in the wild, wild net.

I gotta say this before I lose the thought.  I’ve been playing with Google Sidewiki and an idea just burst into my brain.

First, read this: Google’s Sidewiki page

Then, search google for “sidewiki controversy” and note the opposition to the new communications platform.  Take your time, I’ll still be here.

Now, if you are so politically inclined, you could install google sidewiki, and join or start a conversation on bills that are passing through Washington by going to thomas.loc.gov, searching for–oh, I don’t know–the healthcare bill, and get smart on what it actually says.  Using Google Sidewiki, you can finally leave comments on those pages, so now our elected officials who are cutting-edge enough to have google sidewiki installed can go to thomas.loc.gov and see what the public (or those who have sidewiki installed, anyway) are saying about sections of bills being passed through congress!

I’m gonna try it.

So I’ve been dicking around with my linux ubuntu server. I installed postfix and courier-imap to set up an IMAP server on my network so whenever I feel like switching email clients I don’t lose all my mail. Well, the first thing I apparently have to do is make sure postfix is working right, and that involves configuring my /etc/postfix/main.cf file.

So I start looking into it, and come to a part where I have to list my external IP address as part of the config file so some kind of loop doesn’t happen. Well… how do I automate this? Here’s the script I eventually came up with:

sed ’s/^proxy_interfaces = .*$/proxy_interfaces = ‘`wget -qO- http://checkip.dyndns.org | html2text | cut -c21-35`’/’ /etc/postfix/main.cf > /etc/postfix/main.cf.tmp

mv /etc/postfix/main.cf /etc/postfix/main.cf.old

mv /etc/postfix/main.cf.tmp /etc/postfix/main.cf

/etc/init.d/postfix restart > /dev/null

I know it doesn’t show up right, but the first line starts from sed and ends with “> /etc/postfix/main.cf.tmp”, and what it does is query that web address which returns my IP as seen from the outside, then replaces the string “proxy_interfaces = blah blah blah” with a correct string that states what my IP address is from the outside. Anyway, I stuck this script in my cron.hourly folder so each hour it gets my external IP and updates my postfix main.cf file accordingly, rebooting my postfix daemon silently after each update.

I know my Linux kung-fu is weak, but I consider this a step towards mastery of my OS.

Today: shell scripts. Tomorrow: kernel programming… again! Just call it the “re-education of TJ O”
