Episode 149: Continuous Delivery with Dave Farley

Craig, Tony and honorary Revolutionist Pete Sellars are at YOW! Conference and sit down with Dave Farley, co-author of “Continuous Delivery” and they chat about the following

  • There are anti-patterns with doing XP at scale, continuous delivery was born from the learnings from that
  • Continuous delivery is just extending continuous integration to more of the software development practice (and continuous integration requires test driven development)
  • Continuous delivery works because it is the application of the scientific method to software development
  • If you work in an iterative, imperative, experimental way and you take continuous learning seriously and take cycle time as a serious measurement you will naturally drive out agile, lean, systems theory and DevOps
  • YOW! 2016 presentation “The Rationale for Continuous Delivery
  • Most common two ways to introduce continuous delivery to your organisation – need to get cover from senior management to make change or you do it secretly at the grass roots – the fast feedback cycle is important (build feedback in about 5 minutes and ready and deployable in about an hour)
  • DevOps is a terrible name – we are talking about collaborative cross functional teams and it is more than just developers and operations
  • Continuous delivery is focused on shortening the feedback cycle from having an idea to getting the idea into the hands of users and figuring out what our users make of the idea – that’s software development, to do whatever it takes
  • Continuous delivery is working in a way so that my software is always in a releasable state, continuous deployment is if all my automation says my software is in a working state I can just automatically push it to production
  • We have data to show that continuous delivery makes high quality software faster, creates more money for the organisations that use it, reduces defect rates significantly and makes people working in that environment happier
  • It changes the way you design, approach databases and the way you test
  • Scott Ambler’s “Refactoring Databases” book
  • Continuous Delivery tools still aren’t mature enough
  • The deployment pipeline is a seriously strategic resource because it is your only route to Production – need to be able to version and test it like any other Production code
  • It’s as much about the culture of the team than it is about the technology, it frees teams up to do experimentation

Episode 148: The Science of Human Personality with Dr. Brian Little

Craig is at YOW! Conference in Sydney and talks science and psychology with Dr. Brian Little, author of “Me, Myself and Us” and professor at Cambridge University and Carleton University and they analyse:

  • Keynote talk at YOW! 2016 “Personalities at Work
  • There are 5 dimensions of personality – OCEAN – openness, conscientiousness. extraversion, agreeableness and neuroticism
  • Biogenic features of personality – neurophysiology, sociogenic and idiogenic
  • We can often act out of character, we are not bound by our biochemistry
  • What are the core projects in your life that drive your behaviour
  • Skeptical of personality tests at work such as Myers-Briggs because the results are not fixed, they are good for starting a conversation but deadly if they conclude a conversation
  • Don’t just ask “How are you doing?” but ask “Really, how are you doing?” to show that you are taking an interest and care in your people and their projects and aspirations
  • We need to look at the research in this space to find exercises that we can use in the workspace to better help and understand our people
  • “Me, Myself and Us” is written for the person who is waiting in Starbucks for that friend that is late again
  • TED talk “Who Are You, Really? The Puzzle of Personality” (it has 6 milliion views – about 5.99 million more than this podcast!)
  • Research is currently looking at the neuro-slant of personality traits

Episode 146: Agile, Architecture and Technology with Rebecca Parsons

Tony and Craig are at YOW! Conference in Brisbane and catch up with Rebecca Parsons, the Chief Technology Officer at ThoughtWorks and the co-author of “Building Evolutionary Architectures: Support Constant Change” and chat about the following:

  • Rebecca’s keynote talk at YOW! “The Past and Future of Evolutionary Architecture
  • Evolutionary Architecture is the next stage on applying Agile practices to software development at the systems level and be able to respond to changes in the environment that affect the architecture
  • Need to determine for your system what constitutes good, fitness functions are the documentation and tests to ensure your system meets those characteristics
  • Need to move the needle on architecture, need to develop tools and techniques to decompose the role
  • Agile Alliance is looking at what it means to truly be an international organisation (there are now affiliates in Brazil and New Zealand), expanding conferences from the large North American conference to OnAgile and Deliver:Agile and member initiatives to support local events such as Agile Open Space, Agile Conference Sponsorship, Community Group Support Initiative and Speaker Reimbursement
  • YOW! CTO Summit talk “The CTO is Dead: Long Live the CTO
  • CTO role is more now to set technical direction by setting up communication channels to mine insights that can be rolled out and presented to the market
  • ThoughtWorks Tech Radar started as a hot technology list of what ThoughtWorkers would love to work on, became a visual radar that is now released twice a year, starts with 250-300 items and they try to get it down to 100 items, something will fade after being in the adopt ring more than twice, the radar is also available as an open source tool or radar as a service
  • Women leave technology at double the rate as men leave technology, mostly because they are not treated well in the environment
  • Anita Borg Institute Top Company for Women Technologists award
  • What does it mean to be Agile in new technologies like machine learning and data science?

Episode 145: Working Effectively with (Legacy) Code with Michael Feathers

Craig is in Atlanta at Agile 2016 and catches up with Michael Feathers, author of “Working Effectively with Legacy Code” and they talk about the following:

  • Working Effectively with Legacy Code originally started as a book about Test First Programming but morphed into a book about the techniques for refactoring code in legacy systems
  • The Pinned Progress Curve – for many people there is no incentive to change so the mean gets larger between the status quo and good practices
  • Agile Alliance Deliver:Agile conference
  • Organisations that have technical founders have a very different character to their work internally, need to make knowledge of the quality of software more pervasive – the business need to understand more about the technical side, and the developers need to understand more about the business
  • Code that has excessive error handling typically has other design problems – benefit in thinking about whether certain things should be treated as errors or not
  • Entropy happens in all systems, including code, so technical debt is not a surprise, need to make the case for hygiene, putting a dollar amount on technical debt does not add much value
  • Use low impact probing to determine whether code is dead
  • Potsel’s Law – an implementation should be conservative in its sending behaviour, and liberal in its receiving behaviour
  • State of quality is improving and there is more recognition to build quality in
  • Property based testing is becoming more prevalent as we move from object oriented to functional languages
  • Holacracy was designed by a software person, Sociocracy talks about applying democratic principles to governance, these are all interesting experiments
  • It can be hard to recognise if something is intrinsically difficult or not something you are familiar with
  • We weren’t really battling waterfall, it was the lack of any process at all…
