Does the "Hypocrite Commits" incident prove that Linux is unsafe?

Tue 11 May 2021 - Paul Sherwood

The recent furore around University of Minnesota’s “Hypocrite commits” research, which spilled over from the Linux Kernel Mailing List and into mainstream tech media, has provoked a lot of discussion about the Linux kernel community’s processes, and arguably provided ammunition to folks who have been saying all along that open source software cannot be trusted.

Hypervisor Not Required

Wed 06 June 2018 - Paul Sherwood
