Blogger Gustavo Duarte cursed in church when he said that learning new programming languages is often a waste of time. He initially called his post, “New Languages Considered Harmful”, a wordplay on Dijksta’s classic paper on gotos, but after the reactions he got, he toned it down a bit and it’s now called *”Language Dabbling Considered Wasteful”.

Two nights ago I had a conversation with Craig McLanahan, among others, in a slightly dubious sports bar near the JavaOne conference site. When the subject of web frameworks came up, an interesting, and probably obvious, angle emerged.

Object-oriented databases complement relational databases in important ways, says Anat Gafni, VP of Engineering at db4objects, the company behind the open-source object database db4o. In this interview with Artima, Gafni explains how OO databases support agile development, and how they co-exist with relational databases in an enterprise.

This week Hudson was awarded the Duke’s Choice Award in the Developer Solutions category at JavaOne. In the space of a couple of years, Hudson has come from nowhere to become the leading contender among Continuous Integration servers. It’s head and shoulders above the other free alternatives, and arguably at least as good as the commercial offerings.

...the Livescribe Smartpen, which comes with a Java-based development kit. The pen is cool: it's a pen with ink, but it also has a tiny camera in the pen-tip that is watching what you write, 72 times a second. It records all of your writing strokes, and also has a microphone built into it so it can record what you hear, too. It's great for taking notes, in ways that is much easier to understand when you try it yourself. But I'll try to explain just part of it here.

Charles Nutter, a Sun engineer who has worked on the JRuby project, commented on PHP in a panel discussion at Sun's CommunityOne conference. I will not join the "PHP vs. Ruby on Rails" "discussion" here, as the comparison of a programming language to a web application framework for another language does not make sense, IMHO. Instead, I would like to comment on two of Charles Nutter's points.

As organizations continue to grow their IT investments (bought, borrowed, or built) and concepts like Business Process Management (BPM) and Service Oriented Architecture (SOA) become more common, the role of Enterprise Architecture (EA) has become more common. Recently, David Linthicum, Mike Kavis, and Alan Inglis each talked about what they see with respect to EA in the industry.

Java was the language designed for us to figure out what was going wrong at compile time not run time. We were supposed to be able to not have to worry about the things that tripped us up in the days of C. I'm not opposed to metaprogramming and not having to catch exceptions and not having to write a ton of template code -- but I'm not sure that Java, the language, should change to accommodate all of these ideas. Also, did we learn nothing from the EJB wars about what can be added to a spec and why?

Quotes Bill Gates: "They also came up with this idea to stop hurricanes. Basically, the waves in the ocean have energy, and you use that to lower the temperature differential. I’m not saying it necessarily is going to work. But it’s just an example of something where you go, Wow." Wow is right. They can patent an idea for controlling Mother Nature without any single shred of R&D that tries to actually accomplish an impossible feat.

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.

Much of the interest in dynamic languages like Groovy, JRuby, and Scala comes from running on the JVM. That lets them leverage the tremendous R&D that's gone into JVM performance and stability. It also opens up the universe of Java libraries and frameworks. And yet, much of my work deals with the 80% of cost that comes after the development project is done. I deal with the rest of the software's lifetime. The end of development is the beginning of the software's life. Throughout that life, many of the biggest, toughest problems exist around and between the JVM's: Scalability, stability, interoperability, and adaptability.

As I said before, I am a supporter of checked exceptions in Java. I think they are a great idea that supports serious software development in the real world. I also think Java’s huge success can be attributed in part to checked exceptions. But this doesn’t mean I like everything about how the Java’s exception handling system was implemented.

Since I discovered it a few years ago, I've been a big Prototype fan. It's simple, and gets the job done with a minimum of fuss. It's not without warts, of course. I still occasionally forget to put 'new' in front of Ajax.Request, and some of the Ruby-like methods share their lineage's arcane naming. When it was new, it was the best thing around, and while it now has competitors, it's certainly not lagging behind.

My slant is that the phenomenon of programmers not reading books could in some cases be a symptom of a deeper shortcoming: the illusion that busyness is equivalent to worthwhile accomplishment. This mentality is exemplified by mottos like "just do it [write code]" and "you're paid to do your job, not think". Its primary activity is scouring the Internet for example code to copy

I had lunch with a former colleague recently, and we were discussing the type of work environments that are conducive to productivity and employee retention. As a psychology major he was able to pinpoint a simple principle that I had overlooked, but that was strikingly obvious. Enlightened by his observation, I wonder now how many in my field wish to adorn a stick-on name tag, and state with anxious resolve, "Hi, my name is Resource. I am seventy-five percent billable."

Also, I've been able to find enough actually interesting and useful talks to keep from going back to sleep and that's an even better sign. In particular, this is starting to show how the "Java community" is growing up and outwards to encompass more than just the same old things.
