#90 Kjersti Sandberg and Charlotte Lyng, Norwegian Developer Conferences

Summary
Kjersti Sandberg and Charlotte Lyng of the Norwegian Developer Conference tell me what goes into organizing four major conferences around the world.

Details
Who they are, what they do. A little about how the conferences started. What is the Norwegian Developer Conference; spreading around the world, London, Oslo, Minnesota, Sydney. How they organize the conferences, finding local partners, crew, contractors, quality over quantity. How the conference grew. Balancing the content of the conference to suit attendees, choosing the conference tracks, choosing the speakers, new and established presenters. How NDC attracts the big names. Why attend conferences when there is so much content online. Timeline of a conference, planning starts a year out. An invitation to Minnesota, Oslo and Sydney.

#89 Mark Eisenberg, Breaking the Monolith

Summary
Mark Eisenberg talks about the very long life of the software monolith, when it started, and how we have been trying to escape it since.

Details
Who he is, what he does. What is a monolith, tell-tale signs of a monolith, coupling and decoupling. Why we built monoliths. N-tiers and monoliths. Software is rarely a green field. Were we ever able to swap tiers. Advantages of a monolith, it's familiar. Companies need a visionary to effect change. Risk raises its head. SOA didn't work, client server didn't work, n-tier didn't work. Successful companies went from monoliths to microservices when they needed to. RPC is from the 1960s, are you running one piece of code on one machine or ten machines. How to get off the monolith, find a visionary. Time to respond to a challenge is very short. Microsoft is a good example of a large company changing.

#88 Aaron Bedra, Threat Modelling

Summary
Aaron Bedra talks to me about threat modelling, why you should do and what to cover.

Details
Who he is, what he does. What is threat modeling and how he approaches it. Types of security, loss of money, loss of life. Should you secure something if it is not valuable. Are we in a post security world? How often your site is attacked. How to decide what to protect. Regulations and breaches. How to protect your system, watch for outgoing data. How to build secure software from the start (it starts with a hug from Aaron!). Hashed passwords are not as secure as you think. Encryption and input validation. How to check third party libraries. Better software practices lead to better security. How much security is enough, "if you are investing more than you could lose, you're doing it wrong".

#87 Veronika Kolesnikova, Xamarin and Cognitive Services

Summary
Veronika Kolesnikova talks to me about Xamarin and Microsoft Cognitive Services.

Details
Who she is, what she does. What is Xamarin. What are cognitive services, why so many services; artificial intelligence vs machine learning vs deep learning, training models. He she got started in Xamarin; it's part of Visual Studio, SDKs and testing tools, Xamarin live player debugging on device. Why use cognitive services, examples of use. Types of cognitive services - labs, vision, face, speech, translator, language understanding intelligence service. Should I train my own model. Recommendations API. It started with Bing, how is it to use, examples. People to follow - Paige Bailey, Seth Juarez. Veronika is presenting at Visual Studio Live, Las Vegas.

#86 Tomas Petricek, Software Correctness

Summary
Tomas Petricek talks about software correctness, its history and future.

Details
Who he is and what he does, his book on F#. Alan Turing Institute. Software as an engineering discipline, software as art. History of errors in software, errors in hardware. Software was never in crisis. Using types to help with correctness, how different languages do it, some complications, a new language would be needed. Upcoming improvements in correctness. Other projects Tomas is involved in.

#85 Mark Seemann, Dependency Rejection, Part 2

Summary
Part two of a two part recording with Mark Seemann on dependency rejection.

Details
No mocking needed for unit testing, command query separation. Do you still use some DI in impure functions; partial applications, Mark is not a fan of DI containers and doesn't know of any for F#. Are partial functions functional, Haskell keeps its impure functions at the edge, "impure-pure-impure sandwich" sandwich - the origin of the word "sandwich", an example of a translator application, don't lose sight of the other tenets of programming, upcoming conferences.

#84 Mark Seemann, Dependency Rejection, Part 1

Summary
Part one of a two part recording with Mark Seemann on dependency injection and rejection in F#.

Details
Who he is, what he does. The new video site. Used to earn from C#, now earns from F# but would like to earn from Haskell; how much dev is going on in F#. Dependency rejection; side effects, purity and determinism. Impure functions. Pure and impure calling each other. Dijkstra, abstractions and monoids.

#83 Steve Elliot, When to Rearchitect

Summary
Steve Elliot, CEO of Agile Craft talks to me about re-architecting software, why it should be done, when to do it, and how to do it well.

Details
Who he is, what he does. When to re-architect, monitor usage patterns, out of date ui, spaghetti code, ratio of bug fixes to new code, not mobile enabled, difficulty recruiting, market opportunity. Making a decision, who gets a say. How to measure success on a long-term project. Practical steps for moving to new architecture. What to start with, easy or hard pieces; what to do next; how to keep the old system going. What about people who don't want to learn new things. Dealing with remote offices. How to keep the project on track and the momentum going.

#82 Jay Gambetta, IBM Quantum Experience

Summary
Jay Gambetta manager for quantum theory and computing at IBM talks to me about the IBM Quantum Experience.

Details
Who he is, what he does. Why is quantum computing different, entanglement and interference. How do quantum computers look, cryogenic refrigerators, close to absolute zero. IBM's history in quantum computing. What is the quantum experience, how a program goes from the cloud app to the supercooled quantum computer; free and open access to 5 and 16 qbit computers; how to write a program (called a circuit); examples of circuits; is 16 qbits enough for real problems. When can we break encryption with quantum computing, why error correction is so important. Popularity of quantum experience, how soon will a submitted circuit run; using python to submit circuits; what is the "Hello World" of quantum computing; how to write a python program for the quantum experience. Community involvement. Future of quantum, becoming a technology, what about the temperature requirements. Chaotic and exciting times coming.

#81 Doc Norton, Better Agile Metrics

Summary
Doc Norton tells me why measuring agile velocity is a bad idea and what to do instead.

Details
Who he is, what he does. "Escape Velocity", why he wrote a book on agile metrics. What velocity is, rate of delivering value to customer, "it is useless", estimates are "bunk". "The business" pushes velocity based estimates. Lack of trust throughout organization. Can we really reduce a complex problem down to a simple number. Anti patterns: more velocity, cross team velocity comparisons, estimating with time, measuring individual velocity. Side effects of metrics. Variable velocity. What should we measure, cycle time and lead time, fixing bottle necks, code quality, team joy. Where does dev ops come in. How to find Doc's book. Upcoming conferences.
