Why Linus is right (as usual)
Last year, some security “hardening” code was added to the kernel to prevent a class of buffer-overflow/out-of-bounds issues. This code didn’t address any particular 0day vulnerability, but was designed to prevent a class of future potential exploits from being exploited. This is reasonable.
This code had bugs, but that’s no sin. All code has bugs.
The sin, from Linus’s point of view, is that when an overflow/out-of-bounds access was detected, the code would kill the user-mode process or kernel. Linus thinks it should have only generated warnings, and let the offending code continue to run. -
Kube-Node: Let Your Kubernetes Cluster Auto-Manage Its Nodes
As Michelle Noorali put it in her keynote address at KubeCon Europe in March of this year: the Kubernetes open source container orchestration engine is still hard for developers. In theory, developers are crazy about Kubernetes and container technologies, because they let them write their application once and then run it anywhere without having to worry about the underlying infrastructure. In reality, however, they still rely on operations in many aspects, which (understandably) dampens their enthusiasm about the disruptive potential of these technologies.
One major downside for developers is that Kubernetes is not able to auto-manage and auto-scale its own machines. As a consequence, operations must get involved every time a worker node is deployed or deleted. Obviously, there are many node deployment solutions, including Terraform, Chef or Puppet, that make ops live much easier. However, all of them require domain-specific knowledge; a generic approach across various platforms that would not require ops intervention does not exist.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
