Multi-language support pprof Summary References preface 4 Build Web Application with Golang Purpose Because I'm interested in web application development, I used my free time to write this book as an open applications. For those of you who are working with PHP/Python/Ruby, you will learn how to build a web application with Go. For those of you who are working with C/C++, you will know how the web works. I believe binary file of our package. How do we use it? Obviously, we need to create a new application to use it. Create a new application package called mathapp . cd $GOPATH/src mkdir mathapp cd mathapp vim main

We’ve done a lot. 2. 2014 / 2015 - 50% of our BUILD APPS ISN’T JUST ABOUT... IT’S MORE LIKE... THINGS TO CONSIDER 1. The boundary of the application a. Does it cross over into website, store, other applications, conversation… b. Or is it new NATIVESCRIPT DO? Cross-Platform 2012-2014 - The Opportunity/Fear Gap High Content/Fluidity of Application Low Budget Missing Skillset Number of Channels Used Highly Captive Users (touch points) Native

���� Kubernetes Container centric – bottom up. Container is the primitive. Other primitives such as replicaset, deployment are built around containers. YARN Application centric: top down. Scheduling sequence: sequence: Queue -> user -> application -> container request ������������� kubernetes Based on api-server watch mechanism Everything stored in etcd YARN Based on RPC Only application-level metadata persisted

notesABOUT ME • Programming in C++ since 1999 (Professionally since 2005) • Worked in Embedded and Application Development • Since 2013 in AAA Game Development • Representing myself • Examples in this talk compress • Developer iteration time 7Key differences between game and data building Game Code Frame centric Minimise frame time - fast frame rate Eliminate frame time spikes - remove jitter Lag & jitter break the job system to synchronise instead 35Next optimisation technique Avoid blocking with thread-centric sync in jobs Mutex, SpinLock, blocking IO Worst thing to wait on lock Prevents other jobs from running
