Software Best Practices: How to get the bugs out of your embedded product
Просмотров 3393 года назад
Lecture from 2021 Embedded Online Conference (hope you can join us next year!). What approaches really work for development and especially shaking out the bugs? Test-driven development? Simulation? Code and design reviews? Memory access checkers? Scripted tests with coverage analysis? Dumb Luck? This is case study of a project to 'fix a small setup bug' in an existing product, which proved a we...
Software Best Practices: Testing and Testability
Просмотров 2404 года назад
Course by Dave Nadler. A series of case studies (Socratic discussions) on fixing engineering projects gone bad, plus discussions of how to roll out Best Practices including testing across an organization. Covers economics and practical points of testing and integrating testing with development. This video is the course as taught to part of an engineering team I led, as prologue to a successful ...
Bail-Out Aftermath - Lessons Learned (SSA 2020 Convention)
Просмотров 4,2 тыс.4 года назад
On June 21, 2018 Dave Nadler and Spence Chanthavane had to bail out of Dave’s ArcusM. What happened? More importantly, what safety lessons can we learn from this accident and its aftermath? Dave and Spence will discuss the accident, aftermath, and things we can do to improve safety. Speaker Bio: Dave Nadler Dave has flown 4500 hours in sailplanes, mostly competition and cross-country, including...
Motor-glider Unreliability: Examples, Systemic Problems, Ideas (2020 SSA/OSTIV Convention )
Просмотров 6 тыс.4 года назад
Motorgliders are horribly unreliable. When the motor runs and nothing breaks, we are justifiably astonished. We do post-flight inspections just so we have a prayer of the thing working next time. The high accident rate shows pilots don’t treat landing as plan A, because the motor works just often enough that we’re tempted to rely on it. Electrics are offered as a panacea but they have plenty of...
