Gah, stupid brain. I need to remember that the modified pattern space after a series of sed commands will only be printed and deleted right away if that modified pattern space doesn't match the addresses of any later commands. If it does match, it might get further modified and then not printed. Stick ;p;d after the series of commands to avoid that, and not spend an hour scratching your head.

In more interesting news, I've been having fun with new Fedora releases. I upgraded my desktop to F17, because it's not possible to upgrade straight to F18 from F16, but once there I found it so miraculously beefy I decided to keep it. On x86_64 F18 doesn't offer me much that isn't in F17, and what I really want is glibc 2.17 which includes the most excellent change I asked for, but isn't in F18. Following the advice of freenode's #fedora-devel I've got a mock chroot where I can use rawhide, so that I can make some changes to libstdc++ so that a high-resolution std::system_clock will be enabled by default on systems using glibc 2.17+

I have, however, installed F18 (beta) on the shiny ARM chromebook I got for xmas, thanks to lots of help from #fedora-arm. That's a huge improvement on my ageing eeepc netbook. Kudos to the Fedora ARM team on excellent work.

I've also got round to sending my paperwork to the FSF so I can contribute to GDB, which means I should resume working on my patch to teach GDB about C++11 rvalue references. That's been on hold while I sat on the paperwork, wrote a C++ standard proposal and started work on my talk for this year's ACCU conference. (If my wife wasn't working so hard on her studies she'd probably be asking me to stop all these extracurricular activites by now!)
