[$] Much ado about debugging

Recently, an interaction problem between systemd and the kernel was
reported. After a calm discussion, developers of both projects found ways
in which behavior could be improved and set about coding up the solutions.
The technical press was filled with glowing reports on another success of
collaborative problem solving... or, perhaps, most of the preceding text is
entirely fictional and the systemd "debug flag" problem spiraled out of
control in several ways at once.

St. Pierre: Xwayland

Jasper St. Pierre writes about the
Xwayland back end
, which has been merged into the X server core sooner
than had been expected. "So, why did it succeed so fast? To put it
simply, Xwayland has been completely rearchitected to be leaner, cleaner,
faster, and better than ever before. It’s not done yet; direct rendering
(e.g. games using OpenGL) and by extension 2D acceleration aren't supported
yet, but it’s in the pipeline." Lots of details can be found in
the article.
