This is my home in the virtual world, where I write
about things that I want to share. The freely available software that
I've written as well as some of the photographs I've taken over the
years can also be found here. Please use the navigation links on the

PostScript (in the form of ghostscript) was for me the first way to generate
vector graphics outside of a CAD program. I have several hundreds of figures
written in PostScript for inclusion in e.g. LaTeX document.
Later I’ve started using other programs like metapost and asymptote.
But in a sense, I’ve always been dissatisfied with them.
When the book Mathematical Illustrations was mentioned on hacker news, this
re-kindled my interest in PostScript. And I learned some valuable lessons from it.
In this article I will try to document how to with with the FT232H using
Python on FreeBSD. I will be using the Adafruit FT232H breakout board.
Note that since I’m using FreeBSD, the library provided by FTDI doesn’t work.
However, the library provided by Adafruit was written for Python 2, and
doesn’t work with Python 3. I tried tinkering with it a bit to get it to work
with Python 3, but that did not work out. In the end, I went with pyftdi
since it doesn’t require a native library and it just works.
After upgrading a laptop to 12-CURRENT, I had problems with firefox 57 choking on
let firefox create a new one. That solved the problem. But with that I lost my
noscript settings and my bookmarks.
