Logitech mouse and Linux

Finally found a page which includes some instructions on how to get all those fancy buttons working on my Logitech mouse.

A weird little bug…

Yup. There is a weird little bug in numpy… sort of. You only need to watch out for it when subclassing numpy arrays (assuming that the subclasses you are using have avoided it.) Check out my stack overflow post about it. I’m not 100% sure, but it might just be a Python 2 thing.

librdmacm errors when using openmpi

This information can be found elsewhere, but I figured that it’s worth reposting. The bottom line here are errors that look like: librdmacm: Warning: couldn’t read ABI version. librdmacm: Warning: assuming: 4 librdmacm: Fatal: unable to get RDMA device list ————————————————————————– [[13473,1],0]: A high-performance Open MPI point-to-point messaging module was unable to find any relevant …

On level sets of the Lorentzian distance function

The paper in question quotes reference “[1]” a lot. Reference [1] of the paper is “Particle physics and inflationary cosmology“. A book for which some of the pages referenced are in the index or bibliography. I think the correct reference is “Global Lorentzian Geometry“. If you’ve stumbled here then no doubt we’re doing research on …
