Libre Graphics World looks at the use of Blender in 3D printing; the recent 2.67 release includes a "3D printing toolbox." "While Blender cannot help with making actual devices easier to use, it definitely could improve designing printable objects. And that's exactly what happened last week, when Blender 2.67 was released."

It's hard to say why, but May appears to be the month where we look in on PyPy. Three years ago, we had a May 2010 introduction to PyPy, followed by an experiment using it in May 2011. This year, the PyPy 2.0 release was made on May 9—that, coupled with our evident tradition, makes for a good reason to look in on this Python interpreter written in Python.

Commit b0a873ebb, merged for the 2.6.37 kernel, included an out of bounds reference bug that went undetected until Tommi Rantala discovered it with the Trinity fuzzing tool this April. It wasn't seen as a security bug by the kernel developers until an exploit was posted; the problem is now known as CVE-2013-2094. Mainline kernels 2.6.37-3.9 are vulnerable, but Red Hat also backported the bug into the 2.6.32-based kernel found in RHEL6. Expect distributor updates shortly.
