This week Parker and Stephen welcome Brenden Duncombe to the show to discuss the pros and cons of continuous integration and continuous delivery/deployment (aka CI/CD) for hardware. Continuous integration (CI) refers to the practice of automatically and frequently integrating code changes into a shared source code repository. Continuous delivery and/or deployment (CD) is a two-part process that refers to the integration, testing, and delivery of code changes. In theory, CI/CD helps organizations avoid bugs and code failures while maintaining a continuous cycle of software development and updates, but we wanted to learn more about this with Brenden, so Parker and Stephen asked him about CI/CD, and also covered the following:Brenden’s product development background“What is a Director of Customer Engineering?”A brief history of CI/CDWhy it’s the opposite of a nightmareUnit tests for software…how does it work for hardware?Pinball Wizardry A “smearing” vs. a “silo”Test-driven dev benefits over the entire dev cycleIs CI/CD a hard concept to sell?How to make the investment worthwhileThe Hardware Regression StruggleWhen start-ups aren’t really prepared for contract manufacturers What is the ideal development cycle?Building something for your contract manufacturer? Always build twoTeenage Engineering Prep your firmware people with dev boards before the hardware reaches them“Like taking your specification doc and writing a test doc on top of that”Standard Fixtures and Future MacroFab Projects+ more!About our guest:Brenden Duncombe is the Director of Customer Engineering at MacroFab.

This week Parker and Stephen welcome Joe Grand to the show to discuss insecure IoT devices. Inspired by a recent incident where Bosch wrenches were infected by ransomware called DRILLCRYPT, the guys asked Joe to join them to talk about how attackers could compromise the safety of the wrench and cause safety issues for users. Of course, this kind of breach could impact almost any company and its products, and so many topics were covered, including:“Actually, it’s Dr. Grand…”If you’re in attack mode, firmware updates are greatSupply chain issues are hard enough to manage without these security breachesA lack of security can be a business decisionGive me convenience or give me threatsThe hardware industry isn’t as well-versed as the software industry isHow to update 10,000 devices in the fieldHacking is problem-solving (someone tell the FBI)“If you’re not being sued, you’re not working hard enough’Sourcing parts and the risk of getting counterfeit partsWhy a firmware update shouldn’t disable your carResisting Big ToiletSubscription models for…everything…The importance of Design For Security measuresIs getting hacked more of a marketing problem than an engineering issue?Engineering ethics and hacking and designAbout our guest:Joe Grand, also known as Kingpin, is a computer engineer, hardware hacker, teacher, advisor, daddy, honorary doctor, and occasional video maker.

This week Parker and Stephen welcome Kent Johnson to the show to discuss ethics in engineering. It’s a topic that has been alluded to over the course of Circuit Break, but this is the first time Parker and Stephen have delved into it with a real expert on the matter. Yes, most companies have standards and regulations and a moral code that guide them but, as Kent suggests, there are more ethical gray areas in the realm of engineering than we might realize. Topics covered here include:Discovering something isn’t being done properly at your new jobAgreeing to work on something with life-or-death consequences, and you don’t really know what you’re doingBypassing important project safety tests to meet a deadlineCrediting others in an age of ChatGPT and redefinitions of plagiarismHow do you credit and use open source code?Why siloed departments at companies are causing such harm to work dynamicsThe tyranny of the specThe true dangers of “failure” or “gotcha” work culturesAccepting accountability and being willing to changeAvoiding QC by zipping the lip+moreAbout our guest:Kent Johnson is Senior Corporate Advisor for the Religious Freedom & Business Foundation and a management consultant on religious diversity at work. With over 37 years of experience as a Senior Counsel at Texas Instruments, Kent is a seasoned legal expert who specializes in corporate law, ethics, product liability, antitrust, medical/FDA law, and mergers and acquisitions. Since leaving Texas Instruments in 2018, Kent has been helping companies adopt best practices regarding religious diversity and inclusion in the workplace. He is also Stephen’s father-in-law, so this really a family show this week.Relevant links:Kent Johnson (LinkedIn)Religious Freedom & Business AssociationWhy Are Ethics Important In Engineering?Circuit Break Podcast #14: Discrepant DiodesCircuit Break Podcast #410: Eighth Annual MacroFab Star Wars Christmas Special Somehow this Podcast ReturnedJoin the Circuit Break Discourse Community!Thank you for listening to the MacroFab Engineering Podcast!  We’d love to hear what you think of the show so please tweet at us @MacroFab and join our Circuit Break Community for discussions or email us at podcast@macrofab.com.
