I stayed around in San Francisco for one more day after JavaOne, in order to attend the Scala liftoff. The liftoff was an open space style conference (which has a more specific meaning than “unconference”, at least to me). My friend Kaliya Hamlin did a great job of facilitating the day.

Code To Joy has ignited a debate on the topic of You Should Learn New Languages. The post is in response to a Gustavo Duarte post titled Language Dabbling Considered Wasteful, which was carried on InfoQ four days ago. As always, I claim that both sides have their points. When I read Gustavo for the first time, I said to myself, "I couldn't agree more." And when I read Michael's response, I said to myself, "That's totally what I want to say—fifteen years ago." Yes, I'm setting this up as the opinion of the young vs. that of the old.

So I went to the last half of Scala Lift Off on Saturday (only half, because the first half was taken up by my final MBA class. Ever.). I went primarily out of curiosity, not knowing much about Scala or Lift. The main draw was the built in comet support for Lift, which seems to not be a focus in other frameworks... at least not for Rails. We currently use Juggernaut for comet support, but depending on flash is something of a liability (see: iPhone), and Juggernaut itself isn't as smoothly integrated with Rails as i'd like.

We've been working on a new graphics stack for JavaFX, consisting of an integrated 2D+3D JavaFX script scene graph based on a hardware accelerated shader-based immediate mode Java API which fits seamlessly into the OpenKode platform mentioned in my previous post. Of course, this same Java/JavaFX API can also sit on top of OS-specific, proprietary frameworks, such as CoreVideo+CoreAudio on MacOS. Several of our J1 keynote demos actually demonstrated this, namely the two video demos shown here.

The second development chunk focuses on creating documents to index, and munging them into a format to hand off to an external library. There are examples of calling a .NET library from F#, mutable values, function composition, and several other spiffy sounding things.

Haskell is a deep language, and we think that learning it is a hugely rewarding experience. We will focus on three elements as we explain why we think it worthwhile. The first is novelty: we invite you to think about programming from a different and valuable perspective. The second is power: we'll show you how to create software that is short, fast, and safe. Lastly, we offer you a lot of fun: the pleasure of applying beautiful programming techniques to solve real problems

There were several JavaFX-related announcements and demos at JavaOne, not the least of which is the preview release of the JavaFX SDK due in June 2008. As the interpreted version of JavaFX was the prototype for the compiled version, the javafx.ui classes are the prototype for the javafx.gui classes that were shown at JavaOne and will be released in the SDK.

"One of the ways to not fall into the blub fallacy is to regularly consider those ways in which your favorite language is inferior, and could be improved- preferrably radically improved. Now, it should come as a surprise to no one that my favorite language is (currently) Ocaml. So as an intellectual exercise I want to list at least some of the ways that Ocaml falls short as a language."

Some guys at Stanford invited me to speak at their EE Computer Systems Colloquium last week. Pretty cool, eh? It was quite an honor. I wound up giving a talk on dynamic languages: the tools, the performance, the history, the religion, everything. It was a lot of fun, and it went over surprisingly well, all things considered.

Well, the type inference work is not so easy (with performance in mind), but anyway, I've got a bit more progress, at least, the chained member call can now be correctly inferred in a lot of cases. It's some level as Tor's JavaScript for NetBeans now.

Yesterday was the first Scala lift off conference, and I found myself in the middle of conversations I would have never expected. The most unexpected conversation of all—during an encounter between Bayesian probabilists and category theorists—had more to do with quantum mechanics than it had to do with Scala. It was nonetheless representative of a wider phenomenon: Scala has drawn the attention of many very different people.

A new data type appears in version 2.7.1 of the Scala Programming Language called scala.Either (hereon referred to as Either) that is used very often in every-day practical programming tasks. In a similar way that Scala's List and Option types are classes with one or more case class subtypes, so is Either — it has two case classes; Left and Right.

After 25 years of Borland Turbo Pascal and later Borland Delphi, after the Inprise fiasco and Borland ALM focus (a fiasco, as well?), two years after the announcement that Borland was trying to sell its IDE tools, at last we know what lies ahead. And the future looks brighter than it was a few days ago...

While we may have recorded this episode at JavaOne 2008, we spent most of our time talking about more general programming and Java concerns: Scala and functional languages, the freak-out (or lack thereof?) around multi-core programming, breaking around the safe sandbox of the VM to take advantage of operating system features and other technologies, and other topics, like who came up with those epigraphs in the Java Language Specification.

JavaFX.com is up and running! The problem is that it doesn’t work well on most browsers. The small fonts are unreadable when viewed in FireFox or Safari. The site takes a long time to load up. The only thing notable is the transition from one window/panel to the other. Considering almost everybody else can do this as well, I am a little confused what to look at and be impressed about

Four developers took on the challenge to convince the audience of their language of choice -- in only three minutes per round. Guillaume LaForge represented Groovy, Charles Nutter represented JRuby, Frank Wierzbicki represented Jython, and Jorge Ortiz represented Scala.
