New trigonometry is a sign of the times

Filed under
Misc

Mathematics students have cause to celebrate. A University of New South Wales academic, Dr Norman Wildberger, has rewritten the arcane rules of trigonometry and eliminated sines, cosines and tangents from the trigonometric toolkit.

Dr Wildberger has replaced traditional ideas of angles and distance with new concepts called "spread" and "quadrance".

These new concepts mean that trigonometric problems can be done with algebra.

Linux 4.9-rc8

So if anybody has been following the git tree, it should come as no surprise that I ended up doing an rc8 after all: things haven't been bad, but it also hasn't been the complete quiet that would have made me go "no point in doing another week". Extra kudos to Arnd, who actually root-caused the incredibly annoying "modversions do not work with new versions of binutils", bisecting it to a particular change to symbol handling in binutils, and then adding a small one-liner patch to the kernel to work around the issue. We already had other workarounds in place, but it's always good to know exactly what in the tool chain changed to cause things like this.
