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 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.
