Greg Kroah-Hartman has posted a series of patches making some changes around the newly adopted code of conduct. In particular, it adds a new document describing how the code is to be interpreted in the kernel community. "I originally sent the first two patches in this series to a lot of kernel developers privately, to get their review and comments and see if they wanted to ack them. This is the traditional way we have always done for policy documents or other 'contentious' issues like the GPLv3 statement or the 'closed kernel modules are bad' statement. Due to the very unexpected way that the original Code of Conduct file was added to the tree, a number of developers asked if this series could also be posted publicly before they were merged, and so, here they are."

text cairo release 1.16.0 now available
2018-10-20T14:57:45+00:00
After four years of development since 1.14.0, version 1.16.0 of the cairo 2D graphics library has been released. "Of particular note is a wealth of work by Adrian Johnson to enhance PDF functionality, including restoring support for MacOSX 10.4, metadata, hyperlinks, and more. Much attention also went into fonts, including new colored emoji glyph support, variable fonts, and fixes for various font idiosyncrasies. Other noteworthy changes include GLESv3 support for the cairo_gl backend, tracking of SVG units in generated SVG documents, and cleanups for numerous test failures and related issues in the PDF and Postscript backends." More information can be found in the change log.

text [$] Making the GPL more scary
2018-10-18T15:22:43+00:00
For some years now, one has not had to look far to find articles proclaiming the demise of the GNU General Public License. That license, we are told, is too frightening for many businesses, which prefer to use software under the far weaker permissive class of license. But there is a business model that is based on the allegedly scary nature of the GPL, and there are those who would like to make it more lucrative; the only problem is that the GPL isn't quite scary enough yet.
Greg Kroah-Hartman has announced the release of the 4.18.15, 4.14.77, and 4.9.134 stable kernels. As usual, there are important fixes throughout the tree and users should upgrade.

text [$] A new direction for i965
2018-10-17T22:30:08+00:00

Graphical applications are always pushing the limits of what the hardware can do and recent developments in the graphics world have caused Intel to rethink its 3D graphics driver. In particular, the lower CPU overhead that the Vulkan driver on Intel hardware can provide is becoming more attractive for OpenGL as well. At the 2018 X.Org Developers Conference Kenneth Graunke talked about an experimental re-architecting of the i965 driver using Gallium3D—a development that came as something of a surprise to many, including him.

text [$] Secure key handling using the TPM
2018-10-17T16:36:57+00:00

Trusted Computing has not had the best reputation over the years - Richard Stallman dubbing it "Treacherous Computing" probably hasn't helped - though those fears of taking away users' control of their computers have not proven to be founded, at least yet. But the Trusted Platform Module, or TPM, inside your computer can do more than just potentially enable lockdown. In our second report from Kernel Recipes 2018, we look at a talk from James Bottomley about how the TPM works, how to talk to it, and how he's using it to improve his key handling.
