Change Begets Change

Change begets change. Nothing propagates so fast. I've not blogged in a couple of months amid the whirlwind of change that has become my life. I often feel more than a little in over my head these days.


Change is inevitable so best to embrace it, make it work in your favor. That being said, it's important to choose the path forward carefully, and the company you keep, wisely. It's all too easy to make a wrong turn or to pick up bad habits. Can you say gambling?


My life was on a very steady course up until the time I left IBM. That particular radical change was the beginning of many to follow; it was voluntary and good even in hindsight. But it was carefully planned like the rest of my life. The demise of my partner of 27 years, on the other hand, was untimely, arbitrary, and beyond my control. Such things make one reconsider life's carefully laid plans. It's clear that time is fleeting and that one must make the most of today because there is no guarantee for tomorrow. Workaholic Ed died and the phoenix that rose from his ashes took a really good look around. Guess what? There really is time for me to swim 2km every weekday morning. Go figure!

Looking around a little further, I discovered that I have the greatest neighbors in the world. Okay, granted Warren is a bit of a princess.


So's Linda come to think of it.


But they've helped me more in the last year and a half than one could reasonably expect from another human being. For example, they've looked after my girls for countless weeks whenever I traveled; the girls love it next door. Last week, they even threw a birthday party for Else, the most recent addition to my dog collection.


Most important of all, they've helped make my Frank feel more than a little welcome in his new home in Canada.


Warren and Linda are the epitome of what it means to be good friends and I consider myself fortunate for having them in my life.

Looking around further still at what's happening with modeling at Eclipse and beyond is also eye opening the the extreme. Talk about change that begets change! I'm more than a little gratified and relieved to see that it's taken on such vibrant life of its own. I don't need to obsess quite as much about driving the vision of modeling forward. There are so many others who do that job even better. I've learned an important lesson: don't push the river, it follows by itself! As Kim so aptly put it: Eclipse is like family. What a great family and what a great place to be. Thanks Cloudsmith and itemis for helping make it economically viable for me and for all their other great contributions to the Eclipse community.

Speaking of great places to be, it struck me a few months back that I'd much rather live back in British Columbia. I grew up there. My parents, brother, and sister live there. I like the weather better there. I can grow a more interesting garden there. Frank and I can build a new life together from scratch there. I only moved to Ontario for IBM. So I bought a great property with this view.


My house is already sold, I've got a rental house lined up, and I've scheduled my move for the end of May. Of course there are more changes yet to come.

I write this blog today from Berlin, in summer like weather, as I anticipate traveling to JAX in Mainz next week where there's an Eclipse day and a Modeling day. Could life get any more interesting and exciting?

Oh yes, and it turned out workaholic Ed didn't really die, he was merely transformed into a more well-rounded version of his former self. I've spend the past several weeks porting the core EMF runtime to GWT and modifying the generator to produce GWT-enabled models and edit support on top of that runtime. It's all committed to CVS in time for M7, but I've not had time for documentation yet. Modeling in the clouds; stay tuned for yet more change.

How Active is Your Committer Representative?

Now that we're in the middle of an exciting Eclipse board of directors election campaign, you're probably asking yourself, how will I decide for whom to vote? You might well be swayed by folks like Bjorn who are actively campaigning; Bjorn's always got interesting new ideas. Then again, you might prefer Boris' more subtle approach of simply encouraging you to vote; I like that approach a lot! Or you might like Chris' approach of tirelessly and visibly helping to promote our community; how can you not like Chris for that? On the other hand, Doug's more edgy approach could well be just your thing; he's always thought provoking. Clearly it helps to be visible, so I'd better not be too quiet if I want another opportunity to be on the board; I doubt that simply looking pretty in pink will help...

One thing you might consider is how actively involved are the candidates. Here are some statistics about project involvement.






Most of the candidates are quite involved. There are of course a multitude of statistics one might consider, e.g., number of commits. For that you could compare the dash statistics for caniszczyk, bbokowski, dschaefer, bfreeman, and emerks. Great, just what I needed: a sad, ugly reminder of how unproductive my 2009 was; at least 2010 is off to a better start, both personally and professionally. Check out this lovely one-of-a-kind Kim Horne original water color that I recently had framed to hang in my office as a beautiful reminder of the diversity and creativity of our community.


In the end, the choice of representative is necessarily subjective. I'm sure folks will choose wisely based on who most closely represents their own point of view as well as who is most likely to make effective positive contributions. Having seen Chris and Boris in action first hand, I can definitely recommend them for their experience and for having represented the commiters well.

Peripatetic

It was bound to happen: I was finally asked to be a model. I kid you not. The truth is stranger than fiction. It happened at Upper Canada Mall. Leaving a store that sells leather jackets, I was interrupted by a plaintiff "Excuse me sir, would you mind helping us out for a second." It turned out I was just the right build to act as a model for the lady's husband; she and two other ladies were picking a jacket for him. Being incredibly helpful and generally unable to say no, of course I obliged, volunteering my own opinion on which jacket fit best. All the while, visions of an easy life on the Paris runway just standing and modeling flashed before my eyes. But then I started to feel just like a piece of meat and I decided to keep my regular day job where looking pretty isn't all that important.


Life continues to be far too busy. It's pretty much impossible to balance my personal life with all the other demands on my time. I'm writing this post today from Berlin which is in the grip of a frigid winter not unlike the kind one normally expects in Toronto, so I feel right at home. Last weekend I was in Vancouver getting married. Tomorrow I head over to Munich where Peter and I present at OOP 2010; no, I will not be presenting in German though my German is definitely improving, something one might expect when you marry a German. The more German I learn---I can almost follow a conversation now---the more frustrated I am with not knowing more. This coming Thursday Ralph has arranged another Eclipse Stammtisch so I plan to attend that; I'm sure much German will be spoken. Maybe I'll see you there. I just hope it's not so cold.


I don't head back home to Toronto until February 2nd, but I expect to be back in Berlin yet again for the Modeling Code Camp at the beginning of March. Itemis does trainings like this as well. It's unfortunate that more people don't take advantage of the opportunity to get a jump start on exploiting open source technology. It might seem cheaper to muddle through on your own but suboptimal design decisions are likely a much bigger hidden cost down the road. EclipseCon will be yet another cost effective opportunity to learn new things, and yet another reason to travel. There will certainly be a great deal of modeling content. Too bad we couldn't accept more submissions. After EclipseCon I expect a short break in the travel schedule before I head over to Germany yet again for the JAX conference in Mainz. Maybe I should just move to Germany to save all the travel time.

On the Balance

The new year is a time to reflect on how life is unfolding, to chart an effective course forward. Those who are wise consider carefully all the things for which to be grateful so that all the ways in which life inevitably short changes them loom less large. They temper their drive to satisfy their own personal needs and desires with consideration for their impact on the world around them. Life is a balancing act without a simple, obvious, optional strategy. Of course it's better to give than to receive, but only a fool gives to the greedy; something particularly germane in an open source community.


The wise avoid spending in inordinate amount of time focused on all the things around them that might be changed for the better because most of those things are beyond their control, not to mention the fact that "Better for whom?" is not always entirely clear. Instead they focus primarily on the very small number of things upon which they can personally have the most significant impact, always keeping in mind that the easiest things to change, and the biggest source of problems, are themselves.


For me personally, 2009 has been in part an extremely bad year; I've had to learn some painful lessons. Life is short, don't waste precious minute of it. Unfortunately everyone has to learn this lesson their own hard way, based on direct personal experience. I generally did my job poorly, or more positively stated, there's much room for improvement. I'm most grateful to itemis and Cloudsmith for their generous funding of my work and to my family, friends, and the Eclipse community for their support. All things considered, 2009 has also been an extremely good year; I've learned some my lessons exceedingly well and most importantly I've found the one thing I want most of all. On the balance, life is only as bad as you choose to perceive it and only as good as you take action to make it. Let's make 2010 an excellent year!

That Totally Sucks You Big Loser

Suppose you went for dinner at someone's house and they served excellent wine, a fantastic main course, a scrumptious dessert, and a salad that made you want to gag. What would you do?

1. Compliment them on all the good things, overlooking the one bad thing.
2. Explain that the salad literally sickened you, carefully detailing exactly what was so awful about it.
3. Something between these two extremes.
   

Keep in mind that the blue cheese salad dressing might very well be fine quality; the real problem might be that the taste and smell of rotted milk just isn't your thing, i.e., the problem might be subjective, not objective.

It seems human nature to find fault with the world around us. It's not even bad thing. After all, how can one improve anything without constructive ideas for making them better? One must counter that with the fact that it's also human nature to take offense easily to anything that isn't entirely flattering. We generally prefer to hear mostly compliments, especially given the fact that we're getting asymptotically closer to the perfection for which we strive. That's why as children we're taught: if you can't say something nice don't say anything at all. Clearly that's a little too black and white, but that's yet another human failing: to over simplify problems and then come up with simplistic solutions to those. One thing to keep in mind in this drive to achieve perfection through criticism is that focusing on positives, or at least noticing them, generally makes one feel better, e.g., I noticed how lovely these maple trees looked and therefore spent much less time noticing that the wild pigs of Berlin had destroyed the lawn around it.


Given we're all so perfect, of course it's a virtue that we should speak our mind whenever a thought enters it. Every criticism we dish out should be seen as clear evidence of our drive for ultimate perfection. The sharper the critique, the more evident is our keen intellectual perceptiveness. Any mature adult ought to see our commentary as the good kind of criticism, i.e., the constructive kind. Those who do not are, well, over-sensitive, short-sighted losers to be perfectly blunt. With folks like that, one might as well waste time explaining to this water plant that the underwater lily bees aren't about to show up to pollinate it.


Personally I'm more than a little fed up with people complaining about the salad; it tends to ruin the dinner party for the host, and even the other guests who don't share the subjective distaste. It's especially disturbing when the host shrieks back a retort about the gawd awful choice of the complainer's dinner wear. One always has to wonder if the complainers could throw a dinner party or their own, especially given their lack of social graces. I'd suggest they think more carefully about the impact of their criticism before dishing it out. Is it actually valid critique to begin with, or is blue cheese simply not their thing? Most important of all, what good will come from the criticism? Is there perhaps a nicer, more effective way to achieve that goal with an approach that doesn't sound so critical? Sharing your favorite salad dressing recipes without a single word of criticism is probably an approach close to optimal.

Modeling Daze

The Modeling Days have left me in a bit of a daze so I'm way behind with my blogging. The New York Eclipse Modeling Day was hosted by Credit Suisse in the smaller building next to their main tower across from Madison Garden.

Ian Skerret started the day with a quick introduction followed by Joe Wood of Credit Suisse who talked about how modeling is rapidly becoming a central aspect of Credit Suisse's information technology infrastructure. They're very focused on industry standards to help facilitate integration across organizations. Following those quick introductions, I did my stupid modeling talk.

After the morning break, Richard Wood of Credit Suisse presented a case study on model transformation. They're using oAW and EMF. He talked about Gobal Services as Enterprise Java Beans for which service interface definitions were specified as UML class models. It was a quick and dirty solution with the drawback that the UML API was complex to use and hence the templates were difficult to maintain. Using a specialized model to express web services helped simplify the transformation process of producing WSDLs and XSDs. In other projects they used profiled UML to describe the different design layers of a large project, i.e., the presentation layer and the business data layer, which they mapped onto a specialized DSL and from that generated the parts of the application. He also talked about generating a profiled UML instance from a model and talked about some of the lessons learned. The requirements for the model that are needed for generating is often different from the original high level model, so using transformation to produce the more specialized form can help simplify the design. He suggests to avoid generating directly from UML because it's too complex and that complexity obscures the logic of the templates to make them unreadable and unmaintainable. He feels that static content in templates needs to be independently maintained. He also advises to reuse existing technology whenever possible, e.g, the oAW XMLWriter. One of the questions afterward was about why UML was being used at all; the primary reason given was that UML is simply a standard requirement for which there is existing experience and tools.

After lunch, Bjorn Freeman-Benson, Miles Daffin of Morgan Stanely, and I did our b3 talk. It went pretty well I think. The b3 project completed its creation review just last week, so we're off to the races! Our talk was followed by Eike's CDO talk where he explained many of the same things I've seen at the Munich code camp and at ESE, so it's starting to sound simple and familiar.

Moritz's talk about combining graphical and textual views followed the final break. He focused on some of the qualities of good textual notations, e.g., readability and writability, as well as the tooling aspects that further facilitate these aspects, e.g., syntax highlighting and content assist. Then he compared different aspects of textual and graphical notations, e.g., text tends to be presented in its entirety whereas graphics tends to hide much of the model in properties not directly visible.

The day finished with a closing panel where the panel asked the audience questions to stimulate more two-way interaction. All in all, it was a very fun day. One of the ladies I chatted with remarked how great it was to be able to attend a free mini-conference like this. "Usually something like this costs a lot of many," she remarked. Soon it was time to say goodbye to the bright lights of New York.


The Toronto modeling day was fun as well. It follow much the same format and included mostly the same content. IBM's facilities were very nice, but they asked us not to use cameras. It was especially nice to see some familiar faces. I did my stupid modeling talk yet again; people always seem to like it so that's rather gratifying. My build talk was after the break, so basically I talked the whole morning and was very tired after that. Following lunch I attended the MDE talk as well as Mile's AMP talk. Both were very interesting.

I think the Toronto day went even better than the New York; folks seemed more inclined to interact with each other. That same evening there was a demo camp as well, so we had even more opportunities to chat and mingle. If I wasn't so darned tired, I'd have taken a few pictures. With all the excitement behind me, Frank and I were able to focus on setting up this year's festival of lights.


We refuse to be outdone by our neighbors, not that we're competitive or anything.

Do It Better With A Model

Has the spark of excitement in your life slowly dwindled? Do you suffer from performance anxiety? Are you concerned that you won't be able to fully satisfy Helios? Fear not for you are not alone! Fortunately for you, we have a new drug free solution. Forget about all those ads for pills and mechanical devices filling up your spam folder. We have discovered that real live models bring a whole new perspective.


Our carefully selected models aren't merely super, they're versatile and flexible enough to satisfy your every need. Just relax and let them do their thing. Of course if you feel so inclined, you can take control anytime the urge arises. If you aren't yet fully convinced that our stimulating models are exactly what you need, have a look at this testimonial from one our many completely satisfied customers. He's clearly taken aim and hit the mark, and he's not alone.


Best of all, our models aren't merely good for builds, they're good for development in general. Whether you like to do it top down, bottom up, or some other way we've not yet imagined, our models will be there to help you feel like the real developer you've always wanted to be. Your imagination is the only limitation, so take a bit of time to dream of the many exciting things our models might do for you do today. The e4 team has, and now there's no holding them back. Just keep in mind that no problem is too small or too big for our models. After all, I doubt this grand palace was built without the aid of a model.


We're so fully convinced that our models are world class, we've scheduled free modelings days in two of North America's great cities: New York and Toronto. Register immediately for these exclusive events before time runs out! You'll spend a fun filled day learning about b3, Xtext, CDO, AMP, Papyrus, and SAP's exciting new query technology from some of the world's leading experts as well as discovering how these technologies have been effectively exploited. Not only that, all four authors of the EMF book are expected to be at the Toronto event, so bring your books to be signed. At the end of the day, I'm sure you'll agree: it's simply more exciting to do it with models.
