My apologies to any of my subscribers who may have had issues over the past month with my syndication feed.
I wrote a blog post on July 19 about Bitwise Operation Examples. I copied and pasted directly from my command prompt to the text box and accidentally introduced a non-printing character which blew up the feed because it broke validation.
Feedburner hated it, Google Chrome hated it. Firefox didn’t seem to have any problem displaying the feeds posted after the invalid post, which helped me figure out which post was the culprit. I guess Firefox wins on that front.
Luckily, there is http://feedvalidator.org/ which offers a feed validation service which showed exactly where this non-printing character was hiding. It took a while to track it down, so kudos to that site’s developer(s).
Lesson learned: command prompt -> text editor -> browser
