In 1970, Winston W. Royce published a paper “Managing the Development of Large Software Systems.” Later authors cited it as the justification for what had come to be called the "waterfall process." Yet Royce had quite specifically described that process as one that is "simplistic" and "invites failure."That's weird. People not only promoted a process Royce had said was inadequate, they cited him as their justification. And they ignored all the elaborations that he said would make the inadequate process adequate. What's up with that? In this episode, I blame metaphor and the perverse affordances of diagrams.I also suggest ways you might use metaphors and node-and-arrow diagrams in a way that avoids Royce's horrible fate.In addition to the usual transcript, there's also a Wiki version.Other sourcesLakoff and Johnson, Metaphors We Live By, 1980.Laurent Bossavit, The Leprechauns of Software Engineering, 2014.George A Miller, “The Magical Number Seven, Plus or Minus Two: Some Limits on our Capacity for Processing Information,” 1956.CreditsDawn Marick for the picture of the fish ladder.

We all have some ideas about what works in software engineering and what doesn't. But without real evidence and data that is just an opinion. Empirical software engineering tries to answer the question of what can be proven to work in software development. In this episode, Hillel Wayne and Laurent Bossavit will talk about what we know about software development, what we don't know - and the myths about it i.e. what we think we know but really don't.

Impostor Syndrome is a psychological pattern in which people doubt their skills, talents, and accomplishments. Most of us have felt something like this in our careers, whether it's a fleeting moment or a persistent fear that we're going to be discovered as frauds. These feelings can be overwhelming, even debilitating; but, they can also drive us towards self-improvement. This week, the crew talks about their own mistakes, feelings of fraud, insecurities, and how Impostor Syndrome manifests in their own careers. Follow the show!

New episodes weekly on Wednesday. *Triumphs & Fails* * *Adam's Failure* - Adam accidentally destroyed a database by running a migration script on the wrong database ! Thankfully it was a QA (Quality Assurance) database which could be restored - no critical client-data was lost. * *Ben's Triumph* - He's deleted 200K lines of unused vendor code. That means shipping less code to production with every deployment. He also merged one of his unnecessary microservices back into the monolith. * *Carol's Triumph* - She's not dying! Woot woot! She had gotten COVID-19 right on the heels of a kidney infection; but it is currently feeling much better (and is nursing her sons back to health as well). * *Tim's Triumph* - He's been playing around with Redis as a means to make his applications more resilient. One thing he wants to do is centralize his Session management such that he can pushed new code to production without having to reset user-session data. *Notes & Links* * Breaking Bad ( https://www.imdb.com/title/tt0903747/ ) - critically acclaimed TV drama. * Adam Sandler's Click ( https://www.imdb.com/title/tt0389860/ ) - comedy about appreciating your life. * Redis ( https://redis.io/ ) - blazing fast in-memory database and data-structure storage. * PM2 ( https://pm2.keymetrics.io/ ) - a production-grade process manager for Node.js. * Amazon ECR ( https://aws.amazon.com/ecr/ ) - Elastic Container Registry. * Amazon Fargate ( https://aws.amazon.com/fargate/ ) - serverless compute for containers. * GitHub Actions ( https://github.com/features/actions ) - automation tools for your GitHub workflows. * The Push Train ( http://pushtrain.club/ ) - Dan McKinley's presentation on managing the human side of continuous delivery. * Lagom Framework ( https://www.lagomframework.com/ ) - an opinionated microservices framework for moving away from the monolith. * Little Bobby Tables ( https://xkcd.com/327/ ) - classic XKCD comic. * Multi-Stage Builds in Docker ( https://docs.docker.com/develop/develop-images/multistage-build/ ) * Mike Cannon-Brookes: TED Talk on How you can use impostor syndrome to your benefit ( https://www.ted.com/talks/mike_cannon_brookes_how_you_can_use_impostor_syndrome_to_your_benefit ) * WTFs per minute ( https://blog.codinghorror.com/whos-your-coding-buddy/ ) - Coding Horror comic on code quality. * 1 Corinthians 10:12 ( https://biblehub.com/1_corinthians/10-12.htm ) - "Therefore let him who thinks he stands be careful that he does not fall." * GoTime podcast ( https://changelog.com/gotime ) - one of the ChangeLog podcasts. * Mythical Man Month ( https://amzn.to/3mowUIU ) - iconic essays on software engineering. * 99 Bugs in the code ( https://imgur.com/a/sZLJB ) - grumpy cat's take on the 99 Bottles song. * Perfect is the enemy of the good ( https://en.wikipedia.org/wiki/Perfect_is_the_enemy_of_good ) - trap that many product companies fall into. * Neil Gaiman's address to the University of the Arts Class of 2012 ( https://www.youtube.com/watch?v=2OwRUyZMKwI ) - "Make good art". * The 10x programmer - toxic programming myth about unicorn developers. * Ruby Rogues EP 220 with Laurent Bossavit ( https://devchat.tv/ruby-rogues/226-rr-the-leprechauns-of-software-engineering-with-laurent-bossavit/ ) - discusses the book, "The Leprechauns of Software Engineering", which covers among other things the myth of the 10x programmer. * Radio Lab: Lying to Ourselves ( https://www.wnycstudios.org/podcasts/radiolab/segments/91618-lying-to-ourselves ) * The "Peter Principle" ( https://en.wikipedia.org/wiki/Peter_principle ) - people in a hierarchy tend to rise to their "level of incompetence". * The Dunning-Kruger Effect ( https://en.wikipedia.org/wiki/Dunning%E2%80%93Kruger_effect ) - a cognitive bias in which people with low ability at a task overestimate their ability.

Summary Laurent Bossavit talks about the myths like the 10x developer that have grown in the software industry. Details Who he is, what he does. His book - "The Leprechauns of Software Engineering", why he wrote it. The 10x developer, literary archeology. The telephone game, examples in the software world, cost of when defects are discovered. Industry does not have interest exposing faults, why is the word "belief" used in software, is software an engineering discipline, opinions over measurements, how did we end up with manifestos. What should we measure when judging software quality, why measuring bugs are like eating from the garbage can. How to make things better. How to get Laurent's book. Laurent's book recommendations.
In this episode, we interview Laurent Bossavit on the morning after the Joy of Coding conference, May 30th 2015 in Rotterdam. Laurent has over 20 years of experience around computers, spending most of it in startup environments. He consults with software companies on implementing agile processes in their organizations. As a Francophone, you may know him as the co-translator of Kent Beck's Extreme Programming Explained's French edition.
