For my upcoming course on File Format Identification Tools, Udemy wants me to provide a graphic. Here’s what I’ve come up with, applying Udemy’s quality standards. I don’t claim to be a graphic designer, but I think it’ll do the … Continue reading
My current main project is creating a course to offer on Udemy on file format identification tools. As currently planned, I’ll cover file (the command line tool), DROID, ExifTool, JHOVE, and Apache Tika.

To minimize confusion, I’ll refer to the group as J.P.E.G. and the format as JPEG, even though the periods are non-standard. Continue reading
The PDF Association has an article on its site titled “What’s unique about PDF? and why PDF will live forever.” The article claims PDF is “a format of such flexibility and power that it will define the essential ‘electronic document’ concept forever.”
Forever is a long time. No one will think they mean that the last object left as the universe succumbs to entropy will be a disk with a PDF file, but what scale of “forever” gives sense to their claim? In a tweet responding to my skepticism, they offered a clarification:
