Linux Data Link Library for The Ironman Watch

Ahhh… the good old days. I had ones of these DataLink watches when I started flying on my first tech job. It saved a ton of time and helped me reschedule several flights, including one where I was north of the border without my luggage. Forget about cellphones, pdas, and wireless internet connections. All I needed was a pay phone and my watch. Sadly, the battery’s dead now. Maybe as project, I will try to get this working again… without the headaches of Windows 95!

Critical Security Updates to Ubuntu and Debian

Just a heads up to Ubuntu and Debian users out there. There is a major bug in openSSL that needs to be patched on all Debian and Ubuntu systems and you must regenerate your ssh keys. I’ve included some links to the gory details:

SSL in Firefox 3

To my dismay today, I ran into a problem with Firefox 3 Beta 5 on Hardy Heron.  Apparently, Mozilla has decided to put the screws to people who sign their own certificates or use certs not issued by their own domain by creating a four step process to bypass the error message.  Here is an explanation: http://wiki.mozilla.org/Security:SSLErrorPages

I was attempting to access an APC UPS inside my company’s network (translated If I am subjected to a man-in-the-middle attack, it is no one’s problem but mine and my department’s.)  APC signed the cetrificate and I was accessing it by IP address inside my network.

So, explain this one to me Mozilla… Is APC supposed to drop their encryption on their UPS systems or do they just have to pay their employees to rewrite the code so I can go out and buy a certificate for this device?  Do I have to register this with my internal dns so it’s easy to remember the way back to it and the students where I work can memorize it’s name?

Perhaps this needs to be removed out of the final version of Firefox 3 and you can write an extension that makes everything break!

Making Thunderbird Open Hyperlinks in Firefox on Ubuntu

This one was driving me nuts and I finally found a solution. For several weeks, Thunderbird has not been opening links I click on them. I found a solution here: http://ubuntuforums.org/showthread.php?t=502651

  1. Open Thunderbird version 2.0.0.14
  2. Go to the Edit menu
  3. Click on Preferences
  4. Click the Advanced tab
  5. Click the Config Editor button.
  6. An about:config window will open up.
  7. In the Filter box, enter network.protocol-handler.app.http
  8. If the editor is unable to locate it, create a new string and input network.protocol-handler.app.http.
  9. Enter firefox for the string value.
  10. Close out and restart Thunderbird.

Hyperlinks should now be available in your email!
