O'Reilly OSCON Java 2011: Raffi Krikorian, "Twitter: From Ruby on Rails to the JVM"

"Twitter: From Ruby on Rails to the JVM"

Raffi Krikorian

Twitter

At Twitter, @raffi leads the Applications Services group, the custodians of Twitter's core logic -- his teams manage, amongst other things, the business logic, scalable delivery, APIs, and authentication of Twitter's application. Previously, he was the lead of the public APIs as well as being the one of those behind Twitter's Geospatial APIs.

Before Twitter he used to create technologies to help people frame their personal energy consumption against global energy production (Wattzon -- Business Week's "Best Idea" 2008), and also ran a consulting company building off-the-wall projects. At one point, he used to teach at NYU's ITP (created the class "Every Bit You Make") and spent way too much time as a student at MIT and the MIT Media Lab (Internet 0 -- Scientific American September 2004).

Comparing Ruby vs JVM isn't a bit like Apples and Oranges? I guess he meant to say MRI everytime he said Ruby.

Now. what about Ruby(the language) on top of JVM? Is JRuby in JVM 7 performing better than MRI?

[Sam Bessalah]

YEp, the jvm rules. They're doing a good job at being pragmati c at twitter.

Anyone tried the MoboRank (do a search on google)? I've heard many incredible things about it and my cooworker improve his site rank on google by using it.

isn't it spelled Clojure? Talk about hyping something you don't even know anything about :D

[Kamek437]

Did they contribute those gc patches to the ruby community?

[jicksta]

Good talk. I've been a professional Ruby dev for the last five years and, yeah, I agree Twitter has probably has outgrown Ruby. Most businesses need maximal productivity and quality to even get to the point where Twitter-level scaling is a problem. I'll be Mr. Productivity and play Mr. Scaling creatively when that's my biggest challenge.

His point that Ruby can't effectively do many requests in parallel and then aggregate them together is erroneous. I wonder if he's even aware of EventMachine.

[CrazyPheel]

He means server-side java.

[Chnamanjx]

Excuse my ignorance, but what flavor of Java is he talking about? Regular Java Applets?
