On today’s Groovy Podcast, I mentioned that I was teaching a Groovy training class this week at Research Now in Plano, TX. That’s not how I said it, though. I said that I was broadcasting live in front of a studio audience and that they were the most amazingly awesome group I’ve ever encountered. (Yeah,… Read More
Groovy posts in other places
Recently I’ve been writing about Groovy and Grails for my friends at Accelebrate. I do that because: They’re a great client They support what I do They pay me CASH MONEY The only problem is, whenever I post there, I don’t post here. I thought, therefore, that I’d add some links here to let everyone… Read More
If a method arg is a closure, for crying out loud pass it a closure
This is a (mildly) embarrassing post, because it demonstrates how in my transition to functional programming I missed something important. I get it now, though, and I might as well help others avoid the same mistake I made. I teach a lot of Grails training classes, and one question that always comes up is how… Read More
Now Co-Hosting the Groovy Podcast…
When I first starting learning Groovy in a serious way, one tool I enjoyed was listening to the Grails Podcast. Glen Smith and Sven Haiges led a discussion about Grails-related issues on a regular basis. Of course, since they talked about new developments in Grails, they also had to cover new developments in Groovy, so… Read More
Groovy/Grails – Pivotal == Opportunity
The news broke this morning that Pivotal plans to withdraw its financial support from the Groovy and Grails projects by the end of March, 2015. The heads of both projects, Guillaume Laforge and Graeme Rocher, have each blogged about it, with their typical grace, thanking Pivotal for the opportunity and assuring everybody that both projects… Read More
Spaceships, Elvis, and Groovy inject
When I first started learning Groovy, I took to collect pretty quickly. The current trend of adopting “functional programming” practices works well in Groovy, though the names of the methods are somewhat surprising. For example, collect is like map, findAll is the equivalent of filter, and inject is the proposed replacement for reduce (or whatever… Read More
The Reason The Internet Was Invented, or, Cat Pictures FTW
I’ll report about the SpringOne2GX conference soon, but I’m fighting a cold at the moment and the medication has put me in a rather bleary state. Thus, the following bit of random Groovy whimsy… In this post, I’ll use Groovy to access a publicly available RESTful web service, parse the downloaded data, and build a… Read More
SpringOne2GX, Day Minus 3
Yes, that’s a minus sign, because the event in question hasn’t happened yet. This is my first report from the upcoming SpringOne2GX conference, which starts in Dallas, TX next Monday, 9/8/14 (or 8/9/14 for my non-US-based friends). Since there are no talks on the opening day (just an opening keynote and reception), I’m arbitrarily designating… Read More
Responses to “The Closure Of No Return”
I knew as soon as I wrote about implementing a simple prime number algorithm using Groovy that someone would find a more elegant way of solving the problem. In this post, I want to highlight some of the responses I received. In my previous post, The Closure Of No Return, I discussed implementing an isPrime… Read More
The Closure Of No Return
Even in a language like Groovy that is normally so clean and intuitive, there are traps for the unwary. I fell into one again today (in front of a room full of students), and I think it’s high time I documented it, at least so I’ll remember it for next time. I’m teaching a Groovy… Read More
