This is a note to self since the fix is so bizarre and hard to track down. I recently broke bluetooth badly on my Mac Mini which is running Lubuntu 18.04, and took several hours to fix.
I needed a copy of QMake to install MultimonNG on Ubuntu 17.10. QMake is a component of the Qt Framework. It is a utility to automate the generation of makefiles. The generated makefile is then used to build a final application (in this case MultimonNG).
Yet another great interview I can happily recommend featuring the Jazz drummer Dennis Chambers.
I recently came across this interview with the remarkable English drummer / keyboard player Gary Husband.
I first heard Rae Morris on the radio station Chill Radio and had to investigate the artist who produced this exquisite record.
I have open-sourced a fairly comprehensive morse code tutor I have written (and used) in the Ruby language. It goes by the name of CW.
