[$] Time namespaces

The kernel's namespace abstraction allows different groups of processes to have different views of the system. This feature is most often used with containers; it allows each container to have its own view of the set of running processes, the network environment, the filesystem hierarchy, and more. One aspect of the system that remains universal, though […]

After Years of Abusive E-mails, the Creator of Linux Steps Aside (The New Yorker)

A story in The New Yorker magazine may help explain some of the timing of the recent upheavals in kernel-land. Longtime followers of kernel development will find the article to be a mixed bag—over the top in spots, fairly accurate elsewhere.

He described the project and what it means for silicon and device vendors in a talk at Open Source Summit North America 2018 in […]

How the system reacts when, for example, memory is exhausted, makes a big difference in Facebook getting its work done. Tejun Heo came to 2018 Open Source Summit North America to […]

I kinda knew a […]
