New Technologies at AI2

Scala 2.11 -- Why Upgrade

• Because 11 is bigger than 10

• We had to use some code that was only released for 2.11

• Support for 2.10 is slowly disappearing

• Scala 2.12 is almost out

---

Scala 2.11 -- What do we get?

• Faster collections

• Faster compilation

• Separate the chaff (20% smaller library)

  • XML support
  • .NET support

• Improved warnings ("Hello, ${name}!")

---

What a headache -- Who can help?

• Michael Schmitz
• Jesse Kinkead
• Dirk Groenveld

Why use React.js?

• Because Angular is for squares

• Server-side rendering for improved performance and SEO

• Angular.js 2.0 will fork the community

• Still in the "trial" phase at AI2

---

How does React.js affect me?

• Are you starting a new web application?

  • Is it on Aristo?
    • Stick with Angular for consistency
  • Is it on S2?
    • Talk to Sam to see if React.js is best

• Is your name Tony?

  • You are already a guinea pig

Why use Docker?

• Because everyone is talking about it, cool logo

• Docker "containerizes" software and services so they can be run anywhere

  • Do you want to install JPL on a Mac, Redhat, and Ubuntu?
  • Repeatable execution of software in different environments (dev, prod, qa, etc.)

• Docker provides versioning of executable software

---

Where has Docker been successful at AI2?

• S2 distributed pipeline uses Docker to execute non-Scala components
  • We have versioning of executable contractor software
  • We don't have to worry about the ops configuration of individual machines

---

Where else might Docker help out?

• Aristo solver competition

• Easily handling native dependencies on multiple platforms

• Distributing Aristo evaluations

---

There's a lot of momentum

• Microsoft plans to support Docker containers in Windows Server

• Google is embracing Docker on Google Cloud Engine

• Amazon just opened a previous of AWS Container Service

Adios, amigos!
