Java IDEs at the Roundup

Discussions of IDEs, and the special challenges of having choice

The Java Posse has released yet another session from the Java Posse Roundup. I attended the Roundup in March, and we had a lot of great sessions, all of which were recorded and will be released over the next few months. They’re releasing about one a week so that they don’t overwhelm their bandwidth restrictions. Most of the sessions that have been released to date, were sessions that I had missed. The session that was released this week #115, on Java IDE’s, was one that I not only attended but also was responsible for convening. That simply means that it was a topic that I hoped that people would want to discuss, so I put a post-it note on the board, and people came. We had a great session, and I learned a lot.

If you want to download the recording for the session, you can get it at http://media.libsyn.com/media/dickwall/JavaPosse115.mp3, or from whatever you usually use to download such things (I subscribe with iTunes).

Oh, and yes, there’s a little bit of Microsoft-bashing, but also some accolades too. For one thing, it occurred to me that this is not a conversation that Microsoft developers would be having (i.e., which IDE to choose). Most people use Visual Studio, and that’s an appropriate choice. Yes, there are plug ins, but my bet is that 99% of the community doesn’t bother installing them. I suspect that useful things make their way into Visual Studio, much as useful things make their way into MyEclipse and NetBeans. And yes, I’m sure that there are enterprising developers who customize their environments, but I seriously doubt that Microsoft programmers face quite the same number of choices that Java programmers do when configuring a developer environment. That’s not a bash; that’s actually a compliment. Out of the box, Visual Studio is not only usable, it’s quite useful. With the Java tools, there’s not simply “a box”. There’s “the web”. Go forth, young (wo)man, and find your IDE. Then decide how to customize it. This approach is self-selecting, I think. The types of people who have been drawn to Unix and Linux aren’t put off by this approach. They see it as an advantage. I’m not exactly put off by it, but if you listen to my comments during the session, you will realize that I do struggle with the sense that it’s a waste, some of the time, but then again, I love the fact that people are so motivated to build cool tools that can be easily plugged in.

My biggest concerns with this approach are:

1.It’s hard for new developers to get started
2.Young developers, who expect an IDE as part of modern software development practices will be put off and not choose to develop in Java
3.Time spent evaluating and selecting an IDE, and choosing customizations for it is time that I don’t spend solving problems for my clients.

I haven’t looked at NetBeans in a while, and I will (soon) spend some time looking at that again. I’ve been pretty happy with Eclipse and in the spirit of getting work done rather than once again evaluating tools, I was pretty happy to stay with it. But with some of the new features that NetBeans 6 will provide, I’m thinking it’s time to look at it again.

In any case, what I got out of this session after experiencing it both in person and later, as an observer, I took away the following:

1.We all like (and alternately hate) our IDE's. Even if our "IDE" is vi. 😉
2.Everyone struggles to find that sweet spot of plugins to use with their IDE of choice.
3.If you are a plugin "developer", write good docs and promote the tool wisely so that others can learn about it. Don't produce a 1 hr video (not kind to searching). And make sure that the Java Posse knows about your plugin/tool.
4.A rating system would go a long way toward helping the mere mortals among us to help find cool and useful plugins, and shorten our own individual evaluation cycles.
5.nbextras is a good place to look for plugins for NetBeans.

I think that *** said it best. It really comes down to community. Active participation within the community, sharing about tools, etc. is really essential to knowing what you can do better.

Sun Project Blackbox Tour

Tour coming to Southfield tomorrow!

I first heard about the “datacenter in a shipping container” on the Java Posse. Today, I got an email from a local friend that Sun is doing a tour of the “Project Blackbox” in Southfield, MI on Tuesday, March 20, 2007.

This demo/tour is open to the public and free. If you want to sign up, go to http://www.sun.com/events/st/loc.jsp

They are holding these events all over the country.

Sounds like an interesting tour. I’m looking at my schedule to see if I have time to attend.

Swag at the Java Posse Roundup

Cool swag

Is it rude to brag about the swag at a conference? Ah, well, I’m gonna do it anyhow. Next year, I’m convinced that the Java Posse Roundup 2008 will sell out during the early bird registration period, and it won’t be just for the swag.

But it was cool swag.

Cenqua and Google and O’Reilly sent t-shirts. There was a serious lack of shirts in small sizes. Kathy Sierra would NOT be pleased. She’s right … it DOES matter. Even the guys were amused at the number of XL and XXL. Not a small or medium in the bunch of Google or O’Reilly shirts. I didn’t check out the Cenqua shirts (I like their product, though).

O’Reilly sent some books and notepads. But they made the mistake of labeling the box “Dark Chocolate”. OK, the notebooks were great, but the expectation of chocolate kinda set the bar!

Google also sent some really cool flashy pins. Bruce’s company (Mindview) has great floaty pens.

Adobe sent a training video for Flex and a nice travel mug too.

Sun sent developer tools. I hope that I didn’t forget anyone. The swag table was quite laden with goodies. We have some cool notebooks that I could have taken, but the thought didn’t occur to me.

But next year, someone better send chocolate. I definitely know what SRT will take to its next event. Hmm, we’re sponsors of the Michigan Celebration of Women in Computing in a few weeks. Maybe I should see if we still have time to get chocolate!

Java Posse Roundup: Day 3

Thursday, March 8

By Thursday, people were really getting the knack of open spaces conferences. Those who had held back in earlier days were right in the thick of things at this point. People were resisting the urge to lecture, and getting into the collaborative exchange of information that really gives Open Spaces its edge.

The first session of the day, for me, was on UI Design. Joe reminded all of us that it’s a huge mistake to have our data model reflect the UI design, and vice versa. Instead, it’s important to really drill down to what the user needs to do, and solve that problem from a user interface perspective (and to solve the data storage problem in a sound, but separate, way. Nods were given toward OmniSoft’s Graffle product, which sadly I can’t use because it only runs on the Mac.

Next, I attended a session that Tor had convened on nice looking fonts, typography, and pretty user interfaces. This was a bit out of my area of interest, and I had actually thought it was going to be a different session. I hung around for a bit and learned some things about font rendering (like that Java has its own font rendering engine, that Apple uses bitmapped fonts to ensure consistency in scaling, and that fonts look fuller on Macs and PCs than on Linux). I also learned that there’s a different gamma setting on PCs than Macs, by default. At some point, I realized that while this was interesting, I wasn’t really contributing and my interest had waned, so I exercised the Law of Two Feet (a tenet of Open Spaces).

The Law of Two Feet is “uncomfortable” to exercise until you get the hang of it. The idea is that it’s not only your prerogative to leave if you are not interested or participating in a conversation; it’s really your duty. The very presence of a bored or disinterested party brings down the energy of the group. By leaving, the overall energy increases because only those who are REALLY interested are in attendance. I probably would have left sooner, but that this session was in the lower level room and it was pretty comfy down there … complete with couches! Anyhow, I did leave and got some tea and relaxed until the next session. I could have joined another session in progress, but I decided I needed a break instead.

The last session of the day was on the GWT, and I was really interested in that. Robert Cooper has written a book on GWT, GWT in Practice, and he has an refreshing, pragmatic perspective. While he’s clearly a power user, he’s not afraid to say where Flex is stronger, and where GWT and Flex, working together, might offer some advantages.

GWT does play well with other Javascript libraries, like Scriptaculous, Yahoo UI, etc. More GWT wrappers will be available soon as well. Mostly, the toolkit works great for replacing desktop apps with web apps.

I have a friend who writes a lot of server side code and I pinged him when GWT was first released. He jumped on the bandwagon and has been effusive about it ever since. He loves GWT and finds the model very convenient.

Evening Sessions at Java Posse Roundup

Java Posse Roundup After Hours

 In addition to the daytime (morning) sessions, we’ve been getting together in the evenings.  Someone suggested lightning talks in the evenings, and posted a signup sheet.  8-10 talks per night were quickly filled up.

The evening talks were a mix of technical and non-technical.  All talks were limited to 5 minutes.  Well, it quickly became apparent that 5 minutes was a bit too short, so we set the timer for 5 mins and gave the person 1 more minute to wrap things up.

The first night, there was an attempt to record the sessions, but they were highly visual, and since no one was really set up to capture the sessions with Camtasia (or the like), listening might not be all that useful.

So, Wednesday night, we had talks on such diverse topics as:

Thursday night, people got a little bit more creative in terms of talking “outside of the Java box”.  It was a tribute to the format of the lightning talks that several people chose to bring their spouses that evening, and everyone seemed to have a good time.

Those talks included (not complete list):

  • Yahoo Pipes
  • Flex running with Apollo (and communicating between them)
  • Orienteering
  • Java Docs in the year 2020
  • More racing from Joe (book link: http://tinyurl.com/2bd6vp)
  • Optimal letter spacing from Joel (who does beautiful calligraphy)
  • Right brain vs. left brain

We did the lightning talks at the very large house where the Java Posse was staying.  It was really perfect for this sort of a gathering.

On Thursday night, after the lightning talks, the Java Posse surprised us by telling us their intended format for that evening’s recording of the podcast.  As *** put it, “We provide this show for YOU guys all of the time.  How about this time, we just start it off and then go around the room and ask each of you what you thought about the Roundup?”.  Nice idea, but much stress in the room as we all contemplated actually speaking.  All in all, it was really great (for those present at least) to hear what the others thought about the Roundup, the Open Spaces format, the skiing, etc.

On Friday night, it was even more laid back.  Everyone showed up at the Secret Stash (a unique Crested Butte restaurant, that serves interesting pizza).  The menu is online, so I’m able to share our selections here:

ME & MY UNCLE'S PIE
grilled chicken ~ black beans & corn ~ chipotle sauce ~ cheddar cheese ~ fresh cilantro ~ roasted red peppers

KALADI'S FAVORITE
Grilled Assorted Veggies ~ Fresh Goat Cheese ~ and our Balsamic Reduction

We also had a blue cheese pizza, but I don’t see it on the online menu.

We sat at a table on the floor, with pillows.  This was a bit uncomfortable for the (inflexible) guys with long legs, but I was OK!  A good time was had by all, and those who drank a local beer called Mojo gave it high ratings.  After that, we all descended upon Bruce’s house and watched amusing stuff on YouTube, Google video, etc. well into the night.

 

 

Java Posse Roundup: Day 2

Java Posse Roundup: Day 2

Session 1: Java Development Environments

I convened a session on Java Development Environments (IDEs, tools, etc.). My question was, “Is it a benefit or a detriment that we have choice in our tools?”. For comparison, when programming on the Microsoft platform, developers are given tools that work together out of the box. If they choose to add new tools to their arsenal, they can (especially see Jim Holmes book, “Windows Developer Power Tools”, which includes a lot of open source tools for use on the Windows platform.

In any case, as Java developers, we’re not only free to choose our own tools, but sort of forced into choosing and configuring. Yes, there are packages like MyEclipse and NetBeans which bundle things together, but the IDEs have gone back and forth many times in the past several years. I’ve personally tried at least half a dozen. Currently, I’m using Eclipse, but on the recommendation of the group here, I’m encouraged to give NetBeans another try.

The consensus of the group was generally that we’re glad to have options. I’m still left thinking, however, that we spend a lot of time spinning our wheels, evaluating tools, instead of actually solving problems for our customers (or employers).

Session 2: User Groups

The next session that I attended was on User Groups. Graham, a Crested Butte local, is considering starting a user group here, in Crested Butte. He was looking for ideas and suggestions about how to get started, while others were looking for ideas about how to grow their user groups or to keep people coming back.

I held the position of president of the Ann Arbor Computer Society for 2 years, and I got some great advice from past leaders of that group: DELEGATE. I’m not always good at it, but it’s a good objective. Having a strong leader that can delegate tasks to get done is pretty critical, I think. Several (3) of the guys in the session were from Atlanta, and the AJUG has a dynamic and energetic leader, and it sounds like he does a phenomenal job of keeping their user group going. In addition to an annual DevCon, which is well attended, they offer Job Postings for both potential employers and job seekers (JRecruiter). The Ann Arbor JUG also has this, but I want to look at what they’re doing in Atlanta, because it sounds more effective than the blog-like postings on the AAJUG.

Remote user groups (Taos, Crested Butte) face different challenges. There are few area users, and having a JUG may be too restrictive. It sounds like Dean from Taos and Graham from Crested Butte may create a more encompassing group that serves all software developers, rather than limiting to a JUG.

Chris Adamson was also in attendance. He is an editor for java.net, and he offered to help solicit updates for the JUG list that they maintain. GREAT IDEA, since they really have gotten out of date.

The basic “take-aways” from the session were:

1.Start small. None of the big groups started big. We all started with 2 or 3 people who wanted to get around and talk about cool stuff.
2.Have a compelling reason for people to attend meetings. Good content, opportunities to learn about jobs, etc.
3.Mix in local and national speakers, if you can. National speakers provide visibility to the group, while local speakers get experience talking to a group of people.

Some groups charge dues, while others are free. Some are corporate sponsored, others are not. You just have to find what works in your area.

I would love to create a “meta-group” of JUGs or other user group leaders who might communicate on an eGroup or such to toss ideas back and forth. Maybe we can start with the list on Java.Net?

Session 3: Convergence of Desktop/Web/Mobile

Joe Nuxoll convened a session on the convergence of desktop, web, and mobile application development. Questions were raised about how to determine which platform to develop for, or if it made sense to sometimes build a web app that could be used on a desktop. Mobile has its own set of challenges, but even so, we’re becoming more demanding about what we expect in mobile apps.

One real key is that a lot of time users don’t even know where they’re running up against web/desktop boundaries. One good example of this is Google Earth and Google Maps. Google Earth is clearly a desktop app but it accesses the web to get data that Google maps also uses. Sketchup is a nice application that also pushes these boundaries, in connection with Google Earth.

Joe’s pretty adamant about good user interface design, regardless of desktop or mobile or web. Everyone pretty much agreed that we have to use the right tool for the job, and that it’s not always clear what people need when looking at what people are CURRENTLY doing. Sometimes we need to mix stuff up and come up with a new way of interacting with the user. There are some really cool demos from demo.com that really push this envelope.

Java Posse Roundup Day 1

The conference officially begins!

 

The Java Posse Roundup officially started today.  About 25-30 people have gathered here in Crested Butte, Colorado.  Bruce Eckel and the Java Posse together organized this open spaces event, and I’m really enjoying myself so far.   I won’t try to transcribe the sessions here, since the Java Posse will be putting them out in podcast format, assuming the audio is all fine.  It’s a great experiment, and I hope that it comes out great.  

 

The day started out at the event location, with Bruce describing the structure of Open Spaces.  I’ve blogged about that before, and I’m a total convert.  The ability to be able to put up ideas for discussion while at the event, thereby shaping your own experience, has totally ruined me for the eyes-forward (eyelids dropping) conferences.  

 

It always seems a bit strange to newcomers, but those of us who have done this before eagerly rushed over to the board to grab post-it notes and write down ideas for discussions.  We egged on the others, and soon the boards for all 4 days were pretty full, with 4 concurrent sessions. 

 

The first session of the day offered many choices, all difficult to choose from.  I went to a talk on Dynamic Languages on the JVM.  It started out with a discussion about dynamic languages, but quickly headed toward Domain Specific Languages (easy to build with dynamic languages).  At one point, we realized we had diverged, but everyone voted to keep going.  We had a great 1 hour talk that included mention of Jython, Groovy, Spring, Scala, CLOS, LISP, Ruby, tuples in Java, Domain Driven Design, performance of exceptions, and many many more topics. 

 

And, as always a huge number of book references came out of the discussion.  Some were technical, others fun but also offering some perspective to technical things.  I’ll list them here, just for fun (and so that I have a place to look when I want to read a new book):

 

Poignant Guide to Ruby (online book)

Innovation Games (by Luke Hohmann)

The Design of Everyday Things (by Donald A. Norman)

 

That was it for the first part of the first day.  We all headed off to ski, and planned to meet up later at Bruce’s house for a BBQ.  While most people downhill ski at these events, I had a hard time ignoring the Nordic trails, so off I went with another attendee and we skied the “Town Loop” (a free, flat loop in town).  It was great, just what I needed while I was adjusting to the altitude.

 

And yes, after skiing, everyone headed over to Bruce’s, where geek talk went on well into the night.  I finally left around 9:30 pm or so … it had been a long day.

 

 

Web Frameworks Comparisons at the Java Posse Roundup

Java Posse Roundup Day 0

 I’m here in Crested Butte for an Open Spaces conference, The Java Posse Roundup.  The conference officially starts this morning, but we had an “extra session” last night at Bruce’s house.  Graham Ullrich presented his experiences with TurboGears and Django, both web application frameworks written in Python. 

Graham’s experience with TurboGears was in the summer of last year, with about the 0.9 release.  Since then it has been released as 1.0, and I think that the documentation has been improving steadily.

The major drawbacks of TurboGears include:

  1. Kid templating errors are hard to decipher
  2. SQLObject is limited in functionality

Both of these can be addressed now, as you can drop Genshi in place of kid (and Genshi has awesome error reporting), and SQLAlchemy is more powerful than SQLObject (and arguably than the ORM built into Django).

The major drawbacks of Django include:

  1. Incomplete documentation
  2. Newforms development incomplete 
  3. Not easy to understand what to do with static content

The Django project was poorly advised to put a note in the documentation that new projects should use newforms, since there are major pieces that are not implemented.

Overall, Graham reported that his experience with Django was more “pythonic” than his experience with TurboGears.  It’s hard to tell whether that’s because he was using an earlier version or whether it just feels more natural to him.  In particular, he likes the admin interface and database mapping.

Here are some more comparisons of the 2 toolkits:
