Mobilizing your website

I just spent two days adding a mobile front end to a web app a few months ago. It is a reference app called Rabbit Trader, an app that demonstrates our JMS on Rabbit module targeted for vFabric 5.3. To hear more about that module, you’ll have to wait a bit. All I can say…


When testing really matters

This past Tuesday, we had James Ward, principal developer advocate for Heroku, give a presentation on the Play Framework, scala/java, and Heroku at the Nashville JUG. Suffice it to say, it was a really awesome presentation. This was far from a sales pitch, and more like a lets-get-our-hands on this framework and build a web…


Scala makes it easy to evaluate financial problems

Over the past couple of years, I have been innately fascinated by the emergence of scala. Discovering it’s incredible power of type inference, a very extensive collections API, pattern matching, and many other things have been very alluring. Recently, I had a question pop into my head regarding financial data. You see, I often hear…


Scala is EJB2? I don’t think so

I just read Stephen Colebourne’s blog entry that is circulating the twittersphere. I’m about to post some comments, so I guess this means that I don’t “tolerate dissent.” First of all, please don’t pull out the infamous “(0 /: l)(_ + _)” argument okay? I get it that not everyone understands foldLeft’s, but it’s not…


Programming is hard – Part 3

In this latest installment of Programming is hard, let’s talk about abstractions. (For previous readings, see Part 1 and Part 2). I read a column by Ted Neward where he points out how software development is unlike any other industry. We have to deal with abstractions ALL the TIME. As he stated so eloquently, you…


Programming is hard – Part 2

NOTE: You can also read Part 3 of this blog series. The debate about the complexity of scala ensues. As I previously wrote, programming is hard! Trying to conclude how easy or hard scala is based on language constructs isn’t feasible. In a really active thread on the LinkedIn Scala Enthusiasts group, someone posted: …encapsulation…


Programming is hard – Part 1

NOTE: You can read Part 2 and Part 3 of this blog series as well. I have read enough articles debating whether or not scala is hard, and having recently watched a YouTube video clip of a kid presenting his Game Of Life app, I just have to weigh in. Coding in scala isn’t hard….


Please don’t say “don’t do that”

I have been digging for a couple of days on how to build a Scala List inside Java. The blog entries are hard to find. Most talk about converting a java.util.List into a Scala List from inside Scala. That is not what I’m looking for, but what really infuriated me was reading a blog entry…
