jmThis is like watching a train-wreck in slow motion on Groundhog Day. We, in the broader Linux and open source community, have been down this path multiple times over the past fifteen years, specifically with package formats. While there needs to be room for experimentation, having two incompatible specs driven by two startups trying to differentiate and in direct competition is *not* a good thing. It would be better for the community and for everyone who depends on our collective efforts if CoreOS and Docker collaborated on a standardized common spec, image format, and distribution protocol. To this end, we at Red Hat will continue to contribute to both initiatives with the goal of driving convergence.]]>rkt docker appc coreos red-hat dpkg rpm linux packaging collaboration open-sourcehttps://pinboard.in/https://pinboard.in/u:jm/b:2c98c2525622/Performance Co-Pilot2015-02-19T15:27:11+00:00

jmWhile there are many defensible aspects of Systemd, other aspects boggle the mind. Not the least of these was that, as of a few months ago, trying to debug the kernel from the boot line would cause the system to crash. This was because of Systemd's voracious logging and the fact that Systemd responds to the "debug" flag on the kernel boot line -- a flag meant for the kernel, not anything else. That, straight up, is a bug.
However, the Systemd developers didn't see it that way and actively fought with those experiencing the problem. Add the fact that one of the Systemd developers was banned by Linus Torvalds for poor attitude and bad design and another was responsible for causing significant issues with Linux audio support, but blamed the problem on everything else but his software, and you have a bad situation on your hands.
There's no shortage of egos in the open source development world. There's no shortage of new ideas and veteran developers and administrators pooh-poohing something new simply because it's new. But there are also 45 years of history behind Unix and extremely good reasons it's still flourishing. Tools designed like Systemd do not fit the Linux mold, to their own detriment. Systemd's design has more in common with Windows than with Unix -- down to the binary logging.
The link re systemd consuming the "debug" kernel boot arg is a canonical example of inflexible coders refusing to fix their own bugs. (via Jason Dixon)

A federal judge has thrown out a patent claim against Rackspace, ruling that mathematical algorithms can’t be patented. The ruling in the Eastern Disrict stemmed from a 2012 complaint filed by Uniloc USA asserting that processing of floating point numbers by the Linux operating system was a patent violation.
Chief Judge Leonard Davis based the ruling on U.S. Supreme Court case law that prohibits the patenting of mathematical algorithms. According to Rackspace, this is the first reported instance in which the Eastern District of Texas has granted an early motion to dismiss finding a patent invalid because it claimed unpatentable subject matter.
Red Hat, which supplies Linux to Rackspace, provided Rackspace’s defense. Red Hat has a policy of standing behind customers through its Open Source Assurance program.
