Not knowing the tool, again

The same situation came up again in a policy document.

The role of Dr. Feaver in preparing the strategy document came to light through a quirk of technology. In a portion of the document usually hidden from public view but accessible with a few keystrokes, the plan posted on the White House Web site showed the document's originator, or "author" in the software's designation, to be "feaver-p."

Dr. Feaver had not necessarily wanted to be identified publicly, but he was, because he was embedded in the metadata, which I guess originated in an MSWord document that was subsequently saved in a PDF format.

Understanding the tools (or maybe not)

A few years back, the US government released a report on a sensitive incident that included a redacted PDF. Unfortunately, the individual who released the report didn't understand the tools in use and caused a great deal of complication. Know your tools.

LiveMocha

LiveMocha is a website that gives you free classes to learn languages. You complete the lessons and then do the exercises. If the exercises are writing or speaking exercises, people who are fluent or native at the language will check over your work and give you feedback about the exercises and grade your performance. As a member of LiveMocha, they also encourage you to check other peoples work and give them grades and feedback (in a language that you are native or fluent in).

8 Tracks

8 Tracks allows users to hand-craft mixtapes for internet radio use. Users can create personalized mixes and apply categories to them for easy searching. They can also describe their mix and add an icon. Other users can comment on them. While the mix will contain songs chosen by the user, their order changes based on copyright. The music license 8 Tracks uses limits the number of songs in a mix to be skipped. Once a mix has been played, the site uses it's recommender system to play another mix with similar music.
