         "quote": "Early DOS software for patient management",
         "description": "My first software that was used productively was called 'Patient'. I wrote it as a teenager in Turbo Pascal for my mother, who, in addition to being a housewife, also worked part-time as a self-employed physiotherapist. The DOS application was multicolored and could be operated with a mouse. We had an Intel 80386 DX 20 MHz computer with a 1 GB hard drive and a simple dot-matrix printer. With my patient management software, one could not only schedule appointments and do the accounting, but also directly fill out the yellow forms that had to be submitted to the disability insurance (IV) for billing. At the time, my mother was probably the only physiotherapist who sent forms to the insurance not handwritten but neatly filled out by a printer 😀. \n\n ![Patient menu screenshot](patient1.jpg) \n\nThe completely exaggerated title 'Physikalisch-Therapeutisches Institut Ruth Krämer & Co.' was, of course, meant as a family insider joke.  \n\n ![Patient detail screenshot](patient2.jpg)"

+        "description": "Music was always my great love. After high school, I went to the Jazz School in Lucerne, but later decided to pursue a degree in computer science at ETH Zurich. Ear training is essential in music, so I programmed 'Ohr', a software for ear training, which allowed users to practice recognizing intervals, chords and their inversions, scales, and so on. To make it possible to practice on the go (laptops didn't exist yet), the software included a feature for creating exercises that could be recorded directly onto cassette. In parallel, the solutions were printed out so that one could practice with a Walkman and a sheet of paper wherever they wanted. The Sound Blaster card was the first to support speech synthesis and could be used with a text-to-speech command-line tool `c:\\sb\\sbtalker\\say.exe`. So, to keep track during practice, every 10 exercises were announced.  \n\n ![Soundblaster](ohr.jpg)"
