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 When to re-architect, monitor usage patterns, out of date ui, spaghetti code, ratio of bug fixes to new code, not mobile enabled, difficulty recruiting, market opportunity.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.

#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.
