InSCIght Episode 20: Clean Code

Listen to the podcast

On episode 20, we discuss clean code. A few of the primary techniques for achieving human-readable code are tabled, including using descriptive, clear names, not mixing levels of abstraction, and code that does only one thing without side effects. An interesting discussion arises on how clean code relates to collaborative code development. Namely, we explore how code improves by using consistent project style conventions and remaining humble in the face of constructive criticism. It is also observed that a well-designed and easily tested structure is a natural consequence of clean code. Ultimately, this results in low-cost, easily-maintainable programs that work. On today's show our crew of hosts includes:

• Jean-Christophe Fillion-Robin (special guest)
• Luis Ibanez
• Matthew McCormick (moderator)
• Wes Turner (special guest)
• Geraldine Van der Auwera

This week Jean-Christophe Fillion-Robin joins us from Kitware. He is an R&D Engineer at Kitware working in the Medical Imaging, Data Management and Software process areas. He is one of the lead developers involved in the development of Slicer 4.0, a platform for medical image segmentation, registration, visualization, and analysis. Wes Turner also joins us from Kitware. He is a Technical Leader at Kitware working in the Medical Imaging and Bioinformatics areas. He has been developing software since the '80s first as a defense contractor, then as a graduate student, and now as an active participant in Open Source communities at Kitware. Watching the ascendancy and decline of various Software Engineering technologies has given him a great appreciation for well-written, understandable code. We again have Luis Ibanez, who can now can be considered regular panelist. Indeed, he was the easiest panelist to edit, likely because his public speaking skills were polished while recently teaching his course on open source software practices.
