Gil Tene explains latency and how it relates to service and response times, measuring latency, common misconceptions about latency, what to do when a system's latency can't meet SLAs, and much more. 

Gil Tene on Understanding Latency

Summary: For our inaugural podcast QCon chair Wesley Reisz talks to Adrian Cockcroft, who works for Battery Ventures where he advises the firm and its portfolio companies about technology issues and also assists with deal sourcing and due diligence.
Why listen to this podcast
•	Over the last year a large number of frameworks and libraries for building microservices have emerged and we're seeing a lot of rapid change.
•	The stack you choose will often be based on the main language you use, so for example Netflix’s stack is language agnostic but the tooling is very Java-centric.
•	Architectural choices can have a profound impact on success, so some-thing as simple as an overly long timeout with retries can cause your system to suffer from a congestion collapse problem.  Have a large timeout at the edge, and progressively smaller and smaller timeouts as you get deeper into the system.
•	Start with a monolith and move to a distributed architecture when you need to because of team size or to get better separation of concerns.
•	Other disruptive trends include “serverless architecture” like AWS Lambda, and open source itself which is perhaps the true definition of disruptive.

Adrian Cockcroft on Microservices, Terraservices and Serverless Computing

Summary: In this week's podcast QCon chair Wesley Reisz talks to Mads Torgersen who leads the C# language design process at Microsoft, where he has been involved in five versions of C#, and also contributed to TypeScript, Visual Basic, Roslyn and LINQ. Before he joined Microsoft a decade ago, he worked as a university professor in Aarhus, Denmark, doing research into programming language design and contributing to Java generics.
Why listen to this podcast
•	The overall theme for C# 7 will be features that make it easier to work with data, including language level support for tuples. 
Roslyn, the compiler and API, allows a much more agile evolution of the language.
•	The Omnisharp initiative aims to facilitate easier editing of C# code in other editors, including VS Code.
•	IoT and Artificial Intelligence are emerging as key disruptive trends.
•	The release may also include pattern matching for type switching.
•	C# 7 is the first new release of the language to be completely built in the open.

Mads Torgersen on C# 7 and Beyond

In this week's podcast QCon chair Wesley Reisz talks to Matt Ranney who is the Chief Systems Architect at Uber, where he's helping build and scale everything he can. 

Why listen to this podcast:

 - Expanding a company and team at this rate is genuinely hard. Lots of mistakes have been made along the way.
 - Microservices allow companies to grow rapidly but have a cost in terms of aggregate velocity.
 - Uber is gradually moving its marketplace development from Node.js to Go and Java. Java is used for the map services.
 - Aggressive failure testing is used extensively in Uber.
 - Some early design choices - like using JSON over HTTP - make formal verification basically impossible.

Uber's Chief Systems Architect on their Architecture and Rapid Growth

In this week's podcast QCon chair Wesley Reisz talks to Heather Fleming, who is the VP of product and program management at GILT, where she is responsible for not only the customer-facing website, but also back office things from distribution to order processing.

Why listen to this podcast:

- GILT treats every person as an individual, with a skillset that is outside their responsibilities.
- You should be able to be your authentic self wherever you are.
- Google found creating a psychologically safe work environment was key to high performing teams.
- You can kill a great team by taking away their autonomy and empowerment.
- Great engineers that want to be managers are fearful of losing their skill, and great engineers that don't want to be managers are put in those roles and are terrible managers.

Notes and links can be found on InfoQ: http://bit.ly/1U2Wgq9

1m 49s - One of the things that makes the culture at GILT so special is the "ingredients framework" that considers every person an individual, with a skillset that is outside what their title might say and what their role and responsibilities might be.
3m 29s - One of the team ingredients is called "motivator" - the ability to make sure that the team understands what they're working on, and more importantly the "why" and how it's driving business or customer value.
4m 35s - The relationship you have with your co-workers should be deeper than many of us are allowing them to be, because they are like your second family.

GILT VP Heather Fleming on Unlocking the "Secret Sauce" of Great Teams

In this week's podcast Richard Seroter talks to Lisa Crispin who works on the tracker team at Pivotal Labs, and is an organiser of the Agile Alliance Technical Conference. Lisa is the co-author of several books on Agile Testing, and is also the 2012 recipient of the Agile Testing Days award for Most Influential Agile Testing Professional Person.

Richard also talks to Justin Searls, software craftsman, presenter of "How to Stop Hating Your Tests" and co-founder of Test Double, a company whose goal is to "improve how the world writes software."

Why listen to this podcast:

 - Agile is mainstream, and being adopted by big enterprises, but there's a place to help small companies and startups.
 - Cloud Foundry pair testers to write production code with the programmers.
 - Developers have to be focused on right now, testers have freedom to look at more of the big picture
 - People know testing is good and there a lot of tools for it, but some tools are ill-conceived.
 - We need a better language for talking about good QA and full stack testing.

2m:00s - The first XP universe conferences were mainly about XP practices, values and principles, and were attended by developers
2m:17s - Over time, topics moved towards processes and frameworks, and the number of developers who attend Agile conferences has gone down dramatically.
3m:51s - Now Agile is mainstream, it's being adopted by big enterprises, but there's a place to help small companies and startups. That's usually where the innovation comes from, and the Agile Alliance wants to encourage innovation.

Lisa Crispin and Justin Searls on Testing and Innovation in Front End Technology

In this week's podcast Richard Seroter talks to James Shore, author of The Art of Agile Development and one of the original signatories of the Agile Manifesto. Also on the podcast are Llewellyn Falco, creator of the open source testing tool ApprovalTests and co-founder of Teaching Kids Programming, and Rebecca Wirfs-Brock, inventor of Responsibility-Driven Design, as well as the author of books including Designing Object: Oriented Software and Object Design: Roles, Responsibilities and Collaborations.

Why listen to this podcast:

 - A lot of people know how to do TDD and refactoring for the back end, but not for the font, but the basics are the same.
 - The basics of Test-Driven Development are the same for the front or back end.
 - If you don't know what's wrong, you don't know how to fix it.
 - The most common code smells, according to Llewellyn Falco: Clutter, long lines, long methods, duplication, and inconsistency.
 - How do we make, in an agile way, the architectural work visible, and not ignore it?
 - How do you have an incremental architecture and get measurements? If I say to you I'm going to go away for six months and figure it out, that's not very measurable.

1m:10s - The talk 'Agile Engineering for the Web' was about how do you bring typical Agile engineering ideas like TDD and refactoring to the front-end languages.
1m:33s - A lot of people know how to do these things on the back-end, but when you get to the front end a lot of people just throw up their hands.
2m:24s - I see CSS bugs all the time, because it's very hard to refactor CSS without breaking something.
