I used EchoSign for the first time today. It’s Adobe’s online electronic signature system, pretty handy.

Using grep (not sed) to grab IP addresses from Apache web logs
Today I ran the following command to see how many people accessed the ProgClub wiki over the previous 5 hours:
jj5@charity:/var/log/apache2$ grep "GET /wiki/" access.log |
grep "13/Jul/2013:0" | grep -Eo '^([0-9]{1,3}\.){3}[0-9]{1,3}' | sort | uniq | wc
bzr_hookless_email configuration bug
I ran into this bug using bzr_hookless_email, fortunately someone had published a patch which seems to have fixed the issue:

Error: post-commit hook failed (exit code 255) with no output
In subversion I was getting the error “post-commit hook failed (exit code 255) with no output” after trying to configure my post-commit hook to send email notifications. At first I thought the problem must have been related to the mailer, but I ran the mail command manually and it worked fine. Eventually I figured out that the problem was that the hooks/post-commit file hadn’t been marked executable. So it was a simple chmod +x to fix the problem.
Binding Postfix to particular IP addresses
I had a problem where my postfix mail system wasn’t listening on its IP address 10.1.1.123 but it was listening on 127.0.0.1. I checked my firewall settings and made sure port 25 was open, but I still couldn’t connect.
I read an article, Bind Postfix Mail Server To Localhost or Specific IP Address Only, which gave me the hint I needed.
The trick was to comment out inet_interfaces in /etc/postfix/main.cf because it was specifying loopback-only which meant postfix wasn’t listening on its other IP addresses.

Facebook App Development
I’m getting interested in Facebook App development and have found a few things to read:
Adding an app/page to a Facebook Page
I found this article which said to add a page/app to a Facebook Page you need to hit this URL with your two parameters:
https://www.facebook.com/dialog/pagetab?app_id=YOUR_APP_ID &display=popup&next=YOUR_URL
Update: I was trying to add an ‘app’ rather than a ‘page tab’ and it turned out I needed this:
https://www.facebook.com/add.php?api_key=YOUR_APP_ID&pages
