Here are some elements that can be used to build a case: outlining abuse patterns and their reasons, the fundamental problem with creative use of technologies, and its consequences.

Trackback in, valid out (mostly)

Trackback in, valid out (mostly) 06/28/2004 09:41 PM
Jacques Distler: You gonna turn off Trackbacks (which don't declare a charset, and could be sent in any charset imaginable, but very frequently are Windows-1252)? Unless you have a way to guess the charset and re-encode the result to UTF-8, they will invalidate your pages as quick as you can sneeze. It turns out that by design it is rather hard for a string of bytes to accidentally be valid utf-8, unless that string is pure US-ASCII, in which case it doesn't much matter which encoding you presume. ...

Staying valid

Staying valid 05/02/2004 05:01 PM

Andrei Herasimchuk:

There seems no automatic way to keep a site valid with web standards unless you close it off to the rest of the world to contribute to it. I will not do that anytime soon.

There is: I'm doing it. Next Thursday will mark the one year anniversary of my switching to application/xhtml+xml as the content-type header for this site, for user agents that support it. Using that content-type forces Gecko engine browsers to refuse to render pages if they are not well-formed XML, so if a page is invalid I hear about it pretty quickly.

So how do you keep a frequently updated site with data from external sources and user comments valid? There are really only two things you need to do. Firstly, ensure that everything going IN to the system (entries and comments) is valid XHTML. I do that using a simple validation system for comments and a bookmarklet for my own entries. Secondly, any and all data from external sources (my blogroll from blo.gs, blogmark URLs added using a bookmarklet) needs to be entity-escaped before being displayed on the site. In my case, a call to PHP's htmlspecialchars() function is all that's needed.

I'm not saying my system is ideal - the need for well formed markup in comments is a major usability issue even on a site with an audience consisting mostly of web developers. But it's certainly possible to operate a site in XHTML with frequent updates and user comments while staying valid at the same time.

RIM Paid $450 Million For Patents That
Aren't Valid

RIM Paid $450 Million For Patents That
Aren't Valid 04/13/2005 05:18 PM
It was surprising last month that RIM finally gave in to patent hoarder NTP and agreed to pay $450 million to license their portfolio of patents on fairly obvious concepts. This came just a few weeks after NTP paid RIM-competitor Good Technologies to license the same patents. However, while we missed this story last week, Po litech notes that the patent office rejected one of the main patents, and has indicated that it's likely to throw out the rest as well. All this, just three weeks after RIM agreed to pay half a billion to license them. The whole thing sounds pretty questionable. NTP (who might not even really have the rights to these patents) paid one company to license their own patents, pressuring the big fish (RIM) to then license them less than a month before the patent office rejected them. Whoever agreed to this deal on RIM's part really has quite a few questions to answer. They just gave up half a billion for invalid patents on an obvious idea, after the company that might not own those patents had to pay off another company to license them. What was RIM thinking?
