Adobe recently released a new Flash Player version for all supported platforms (including the 64-bit Linux alpha) which addresses a number of important security issues. I suspect that by now, the update has propagated through most distributions’ package management systems. If your Flash Player version (see here) is less than 10.0.32.18, do consider upgrading soon. (After all, we don’t wish to undermine the platform’s rock-solid reputation for security.)

In other news, as you can imagine, today’s xkcd comic made the rounds in the office. That’s good stuff; there are layers of meaning behind those pithy stick figures. I guess this would be a good time to link back to my post about hardware acceleration in Flash on Linux and invite another round of questions that are already clearly answered in that post.
