Anthony will be posting the presentation slides in the next few days on the site, but in the meantime, I'll write a few notes from the meeting.
THe first presentation was on the Sleep (JVM) scripting language by Raphael Mudge. He was a very energetic guy, and it was quite a bit of fun just listening to him. Good work Raphael ! Now, the presentation was great, but I personally am far from being convinced that this is something that I will be investing my time into. Here's the deal:
- I've already dabbled into at least a couple of JVM scripting languages (Jython in the past, and now Groovy). THere is a couple of dozen more scripting languages on the JVM which are all interesting to mess around with. Thus, in order to convince a developer to spend time with the language, a scripting language needs to have a number of different characteristics. Granted, Raphi has quite an interesting character, the conversation with him before the presentation was very engaging. At the same time, as with any open source project, the key factor in whether the project will survive is the size of the community. Now, I know Raphi said that there were a bunch of people using the scripting language; however, as it is with a bunch of other open source projects, typically the top 1-2 contenders in the space gather 90+% of the developer attention and community. Although the other languages are not necessarily doomed to fail, they have to find their own niche and a set of committed developers in order to survive. Granted, it seemed like SLeep already has a niche by being used in jIRCii; however, it appeared that Raphi was the sole significant developer. So, the question is, what happens when/if he loses interest ?
- Raphi specifically mentioned that he's not trying to be all things to all people, and considering that it is a much smaller project and community than the other scripting languages, that is a very reasonable goal. However, in order to win developer mindshare, it seems to me that having a decent size standard library with utility functions and being able to call into the JVM for everything else, it's not enough any more. I'm judging from my personal experience: one of the major selling points of Groovy to me was that it DID have the convenient, easy xml processing, JDBC access, command line interface, etc. etc. etc, all on top of its seamless integration with the JVM.
- Now, this is just me, but I never grokked the Perl syntax. Seriously, this was probably the first language that I looked at when I was first trying to understand what web programming was all about (10 years ago).. and today, I'm still looking at the syntax and it can never fit into my skull...
- A couple of notes on the presentation:
- I didn't quite get it if slee was able to extend the classpath at runtime. Raphi showed thate there was an interactive console (big plus in my opinion, Groovy still kinda sucks in this area); however, one big selling point for me was that at any point I could throw in a couple more jars to the classloader and start loading classes from there.
- Raphi mentioned that it was his intent to have a clear separation between the sleep program and where it calls into Java; however, for me personally, that was a downside. I found the method calls to be kinda cryptic ( I couldn't quite follow what was happening in a couple of nested method calls - I admit, it might just be my fault, as I haven't seen Objective-C syntax on which the Sleep syntax is based). At the same tie, I didn't see any type of bean properties (e.g. instead of doing foo.setBar('baz'), doing foo.bar='baz'), which for a scripting language is a must in my opinion.
- The documentation seemed to be excellent
- All the time when I was looking at the presentation, I was thinking that after NetBeans 6.0 comes out, he should have a Schliemann module for Sleep syntax. :-)
- Runtime size was pretty small , big plus for embedding uses...
Now, the second presentation was the main reason why I went to the meeting. It was about NetBeans by the author of Pro NetBeans IDE 5.5 Enterprise Edition, Adam Myatt. I was really thrilled to meet him as I had heard from Anthony that he lives in the Capital District area, and that he's a big NetBeans supporter. I was also really looking forward to checking out his book as I had read a couple of good reviews. Adam did an excellent presentation, he was on his game, and I have rarely seen someone present so many things in such a tight and organized manner. He did an excellent job at presenting NetBeans to the people who had gathered and received a very positive response - one of my coworkers actually re-installed NetBeans the next day and was trying stuff out with it. Way to go , Adam ! One thing that totally blew me away during the presentation was the relatively small footprint of NetBeans. When he was doing the demo of NB 5.5.1, the memory rarely went above 100 MB, and I was quite impressed since he was doing quite a bit (and his laptop was not the greatest to begin with). Considering that he did everything from UML diagrams to Visual Web Pack demos, I was VERY impressed. Then, when he was doing the NetBeans 6.0 preview, I was even more impressed as it hovered around 50 MB - AMAZING !
I was personally a bit disappointed that I didn't learn too much from the presentation. I understand that I was not the target audience for it, as I've been a NetBeans user for quite a long time, and I knew 99% of the stuff that Adam talked about. He was covering a lot of ground (more width than depth) as was necessary to present to the majority of the audience. But all in all, I liked the presentation and I'm looking forward to the next time we meet up : maybe we might even get a chance to talk a bit..
