Overclocking The Radeon RX 580 Under Linux
Yesterday I posted the initial Radeon RX 580 Linux benchmarks while now with having more time with this "Polaris Evolved" card I've been able to try out a bit more, like the AMDGPU Linux overclocking support. Here are the ups and downs of overclocking the Radeon graphics card under Linux.
Since last year there has been basic overclocking support in the AMDGPU DRM driver that's the kernel driver to all newer Radeon GPUs -- GCN 1.2+ and optionally the experimental GCN 1.0/1.1 support. With there not yet being a "Catalyst Control Center" / "Radeon Software Settings" area for the modern AMD Linux graphics driver, the overclocking needs to be done from the command-line.

| Record Terminal Activity For Ubuntu 16.04 LTS Server
At times system administrators and developers need to use many, complex and lengthy commands in order to perform a critical task. Most of the users will copy those commands and output generated by those respective commands in a text file for review or future reference. Of course, “history” feature of the shell will help you in getting the list of commands used in the past but it won’t help in getting the output generated for those commands.

Linux Kernel Maintainer Statistics
As part of preparing my last two talks at LCA on the kernel community, “Burning Down the Castle” and “Maintainers Don’t Scale”, I have looked into how the Kernel’s maintainer structure can be measured. One very interesting approach is looking at the pull request flows, for example done in the LWN article “How 4.4’s patches got to the mainline”. Note that in the linux kernel process, pull requests are only used to submit development from entire subsystems, not individual contributions. What I’m trying to work out here isn’t so much the overall patch flow, but focusing on how maintainers work, and how that’s different in different subsystems.
