breun writes to bring us up to date on the doings of Jon Lech Johansen, known as "DVD Jon" after he cracked CSS encryption at the age of 15. As reported by GigaOM's Liz Gannes, Johansen has now reverse-engineered Apple's FairPlay DRM — but not to crack it. Instead Johansen's company, DoubleTwist Ventures, wants to license the tech to media companies shut out by Apple from playing their content on the iPod. And, soon, on the iTV. Johansen could end up selling a lot of hardware for Apple.

rbannon asks: "Computer literacy is becoming an increasingly used term in education, and more and more schools are being asked to set computer literacy goals for their students. Unfortunately for too many, it means being able to use Microsoft products, and that's all. However, I see it much differently, and I cannot help but think that computer literacy is all about using computers to be able to communicate more effectively. With that in mind does anyone have any recommendations for computer literacy goals, and how to measure them?"

alurkar writes to tell us that PostgreSQL released version 8.1.4 today in order to combat a security flaw allowing a SQL injection attack. From the article: "The vulnerability affects PostgreSQL servers exposed to untrusted input, such as input coming from Web forms, in conjunction with multi-byte encodings like (Shift-JIS (SJIS), 8-bit Unicode Transformation Format (UTF-8), 16-bit Unicode Transformation Format (UTF-16), and BIG5. In particular, Berkus says that applications using 'ad-hoc methods to "escape" strings going into the database, such as regexes, or PHP3's addslashes() and magic_quotes' are particularly unsafe. 'Since these bypass database-specific code for safe handling of strings, many such applications will need to be re-written to become secure.'"
