Linux: Verizon Yahoo DSL

I got Verizon Yahoo DSL working on my Dad's Fedora Core 4 box. His modem is a Westell 6100. These directions were very help (which is half the point of this post). Here are some notes: The default username and password for the modem are admin and password. It prompts you to change these once you login. When I called Verizon, they gave me some userid and password, but I don't remember ever needing to use them. The tech support at Verizon was from Alabama and spoke English well. I had problems with the DSL not syncing. The DSL light was just blinking. It turns out my dad plugged the modem into a wall jack that wasn't actually connected to anything.

He logged into the modem at 192.168.1.1. He navigated to Maintenance > Remote Access. Once there, he picked a pa

HTML: Escaping &'s in URLs in HTML

Warning: Failure to ignore the following validation warning may result in lost productivity! Concerning Ampersands (&'s) in URLs , the following is what I wrote in the Aquarium documentation: The short answer is, if you have a URL with more than one parameter, you should wrap it with $htmlent when you embed it in HTML if you want to pass DTD validation. If you don't care, then it really won't matter. What follows is an explanation of why I can't make it any easier on you. You must escape &'s in URLs in order to pass DTD validation. Per the spec, a browser could look at http://a.com/?a=b©=2 and interpret the ©= as part of value of the a variable instead of a new variable named copy; because © is an HTML entity. To handle #1, Aquarium use to escape the &'s in every URL automatically. However, #2 broke redirects if you redirected to a URL with more than one parameter. I so rarely did this, that I didn't know about the

Python: Fun with Classes
