System Information Scripts for Gnu/Linux

Somebody tipped me off to two useful software tools which display detailed system information. This is especially helpful if you are making a tech support forum post and want to provide detailed information about your system. The first is inxi:

First, you need to run the commands sudo update-usbidsand sudo update-pciids, then inxi -Fxz to get the interesting information.

The other command is neofetch which gives a condensed description of your desktop environment and some other basic system information:

Neither of these programs are likely to be installed by default on a system, but they are likely to be in your distro’s package repository.

Beautiful Complex Number Traces

I got a lot of work done on the bookkeeping, but I couldn’t go to bed without playing with the complex number plots some more. I found an a way to produce some attractive plots. First, I needed this additional function, to make experimentation easier:

(define (complexplot f m n)
    (map (lambda (n)
           (complex2vec (f n)))
         (range m n)))))

The idea I came across was taking the standard unit circle rotation, and multiplying that by samples of the cosine wave:

If I change the “sampling rate” to various fractions of Pi, I get other interesting geometry. Here is Pi/4:
