Following up on a long-standing desire to get domain knowledge out of our heads and onto paper, a colleague and I engaged in writing our first state government pattlet. We spent about two weeks of our spare time putting together an abstract approach to case transfer based upon our varied experiences. We finally have a draft version which we feel comfortable sharing online.

As far as I know, this is a first-of-its-kind endeavor for state government. We drew heavily on Fowler’s Analysis Patterns: Reusable Object Models as background material for documenting the patterns. The underlying analysis, design, and approach are all original, though. Please understand that the pattlet is not perfect. We’ve marked it as a 0.1 version to reflect its state and we intend to update it over the next couple of weeks.

We would really appreciate your feedback on the pattlet. Specifically, we’re looking to understand if there are important case transfer nuances which we missed, flaws in the analysis and design, or significant domain details which might shed new light on how to approach this problem. I know that most people feel very comfortable with email but I ask you to please consider using the comments section on this page. That way, everyone can benefit from your insights.

Note that the pattlet is licensed under the Creative Commons “Attribution Share-Alike” license. This license falls along the lines of common open source software licenses, allowing you to modify and re-disseminate this as you see fit, so long as you attribute the original work to us and any new work goes out under the same license as the original. We plan on distributing future pattlets under the same license. It seems to be a happy compromise between rights and reuse.

Right now, we are only giving access to the final product in PDF format but we have kicked around the idea of hosting sample code, pattern documents, and design models on a Subversion share. Let us know if this would be interesting or if we’d just be wasting our time in this endeavor. Finally, you can find the pattlet by clicking on the link below.

The nominations for the 2006 NASCIO state government recognition awards are now available online. There is some really interesting and innovative stuff in here. 

The article summary “Microsoft vs. Open Source: Who Will Win?” from the Harvard Business School (HBS) Working Knowledge magazine bubbled up on the del.icio.us most popular list this morning. Being that this is one of the “classic debates”, I felt compelled to give it a read. As one might expect of an economic publication from HBS, the material is relatively academic in nature. Some of the suggestions for folks in Redmond to remain competitive with the open source community sound great in theory but are unlikely to ever cut it outside the ivory towers. Price discrimination on Windows software is one repeated suggestion. At first glance, this appears very logical, since the marginal costs of distributing additional copies of Windows are near nil. However, this would lead to a very rapid deterioration in pricing structure  leaving little or no pricing transparency. People are agreeable with paying $300 for an iPod because they know that everyone else is in the same boat. People hate contracting for packaged software and buying cars because they always feel like they are getting screwed by the salesman who uses some secret formula to determine the price of the goods. Is this a perception that would increase Microsoft’s ability to remain competitive? I highly doubt it.

Aside from the purely academic nature of the write up, what irked me more was the choice of protagonists in this story. Microsoft versus Linux, Java versus .NET, scale up or scale out. These debates are just so passé. Large organizations don’t care about Microsoft versus open source – they buy software to minimize switching costs; reduce staff retraining, retention, and hiring costs; and to have a vendor to hold their hands when times get tough. Average PC buyers like my parents don’t care about Microsoft versus open source either – they want something that is easy, that meets their simple needs, and that runs. If the cost of this is bundled into the cost of the PC itself, they are blissfully ignorant of this fact. Most importantly, perhaps, is that Microsoft and the open source community are increasingly ambivalent.

Microsoft, despite its insistence to the contrary, is spending money hand over fist to catch up to Google and Yahoo. Yeah, these two competitors might run on open source software but that’s not what’s worrying Microsoft. It’s their business services and advertising revenues that has Microsoft concerned enough to plow money (to the tune of $500 million in FY ’06) from its cash cows, Windows and Office, into the risky venture they refer to as Windows Live. Linux, and its open source brethren, are taking on lives of their own in a world where the PC is likely to be marginalized in the not so distant future. Internet appliances, consumer devices, dedicated control systems and other “embedded applications” is one area where Linux shines.

Apparently someone cares about Microsoft versus open source though – those who funded the research. I couldn’t derive who that might be from the brief interview with the study’s authors but I’d be interested in finding out.

If you haven’t seen the materials yet on the Destiny USA project, it’s worth giving them a look. The official site is a masterpiece of Flash animation and in the Wikipedia entry, as always, you can find all of the details. The goal of the Destiny project is to create a one-of-a-kind eco-tourism complex encompassing shopping, entertainment, dining, and hotel accommodations in Syracuse, New York. The shopping complex would surpass the Mall of America as the country’s largest mall. The “green” touches included everything from a 100% fossil fuel free / sustainable energy operating goal and organically grown food in the restaurants to a glass-enclosed indoor park and 20 acre artificial lake. In addition, there are plans to create a research laboratory near Destiny for research into renewable energy, security, sustainable design, and more.

Destiny has received limited press outside of the upstate New York area but it deserves a whole lot more exposure, in my opinion. I found out about the project originally during my interviews with ThoughtWorks, which had been awarded the system integration contract for the Destiny project. Even after I decided not to accept the job offer from TW, I couldn’t get Destiny off of my mind. Now almost two years hence, I still find the time almost every week to see what’s up with Destiny.

Unfortunately, the Destiny project has been mired in red tape and controversy since it was first announced. Over the long term, financing has been the project’s biggest woe. At least one component of the combined Federal “Green Bonds”, state and local tax breaks and creative financing mix seems to be in question at a particular point in time. The biggest challenge that Destiny has faced since I’ve been following the project revolved around their rather unique attempt to buy out, at a fixed rate, the existing businesses that occupied land Destiny was claiming under eminent domain. Lots of fodder for an interesting legal and economic debate that’s done nothing but further impediment any progress.

What befuddles me most is that the people of Syracuse and the nearby communities are not breaking down walls to make this happen. I understand how one could have reservations about this project. It’s risky, capitalistic, would increase traffic in and around Syracuse, and could redefine the entire upstate New York economy. So why would anyone support this. Well, it’s risky, capitalistic, would increase traffic in and around Syracuse, and could redefine the entire upstate New York economy. Did I mention lots of high paying jobs and a mew source of tax revenue? Did I mention the cutting edge research laboratory that could make upstate New York the Silicon Valley of renewable energy? Did I mention that all of these new facilities are replacing an old brownfield that no one else wants to touch?

The SEP is based roughly upon the Rational Unified Process (RUP) and Microsoft Solutions Framework (MSF). Those looking at the sample assets will notice the similarities with the standard RUP templates. The process component of the SEP is specifically vague, leaving decisions such as formality versus agility, process activities, and roles to the projects employing the SEP. In particular, projects have several options for SEP customization including document-driven (RUP-style development case), local modifications to the process, or modifications with intent to contribute back changes to BSCoE for inclusion in the master SEP distribution. The SEP is conceptually similar in some ways to Ivar Jacobson’s new Essential Unified Process (EssUP). However, whereas the EssUP variability comes through the selection of practices, SEP’s variability comes through the selection of artifacts. 

For those of you thinking of creating your own software processes, I can only recommend the experience. Using the RUP and the Rational Method Composer or the MSF and the new Team System templates, although educational, is not an easy process. This is especially true if you intend to employ lightweight, agile processes on your projects. In this case, modifying the base processes from the RUP or MSF is tantamount to carving a chess piece from a sculpture sized block of marble.

Fortunately, as always, there are many that have gone before us in this endeavor. The sources highlighted below were of great help to us in the creation of our process and are highly recommended whether you require guidance or are just looking to better understand software engineering processes in general:

• Scott Ambler’s Writings – This guy is truly the best place to start when you’re looking for anything process related. All roads will eventually lead through his work. Particularly interesting are Scott’s Agile Unified Process and his Enterprise Unified Process. The former is a lightweight version of the RUP focusing on test driven development, agile modeling, agile database techniques, and refactoring. The latter is an extension to the RUP covering enterprise disciplines not mentioned in conjunction with many software processes such as portfolio management, enterprise architecture, strategic reuse, and software process improvement. In addition, it adds two new phases to the RUP, production and retirement.
• Philippe Kruchten’s Books – The two Addison-Wesley Professional books Rational Unified Process Made Easy and Rational Unified Process: An Introduction are seminal works on the RUP. Often overlooked is Software Engineering Processes: With the UPEDU, a book that runs through an educational version of the Unified Process with some pretty decent explanations and online examples.
• Craig Larman’s Books – Craig’s books, although not focused on process engineering or the intricacies of processes, convey an awful lot of information in real world contexts. Agile and Iterative Development: A Manager’s Guides is one of the best ways for non-techie types to get their arms around lower ceremony development processes. Applying UML and Patterns focuses on modeling and design patterns but does so in the context of a process using the Unified Process infused with Agile methods, making it a source of great contextual information.

In addition, we have been picking up reference artifacts along the way to illustrate best practices and real world examples. One of the artifacts that I fell in love with was the Yummy SAD, available online as HTML and downloadable in document format via FTP. This is one of the most generic, understandable, and widely-applicable examples of a software architecture document (SAD) that I have come across. One of the big selling points of the Yummy SAD is that aside from just being an artifact, it also comes with an approach to architectural decomposition. In particular, it espouses an architecturally significant use case / quality attributes based approach to documenting and realizing your architecture. Explaining software architecture in this fashion has helped me clarify the relevance and importance of the SAD on more than one occasion.

Please feel free to share any best practice artifact references or software process tips that you might help accumulated over the years in the comments section below.

Just as I was doing a bit of mindmapping of ideas around Internet and societal convergence, my RSS reader buzzed with a new post from Dion Hinchcliffe on Social Computing and Internet Singularity. Dion didn’t go into great details; referring instead to ideas he had articulated in earlier posts. His posting was, however, enough to prompt me to pull together my thoughts, give them a bit more structure and then send them into the great wide world to begin a life of their own.

The idea around Internet singularity, to reuse the quote that Dion referenced from Microsoft’s Dr. Gary Flake is “the idea that a deeper and tighter coupling between the online and offline worlds will accelerate science, business, society, and self-actualization.” “Wow, is Flake talking about true, top-of-the-Maslow pyramid type self actualization” you might ask yourself. I can’t say for sure since self-actualization means different things to different people. To me at least, it appears that the Internet, in its many incarnations, enables the creativity, knowledge, and energy of billions of people to be set free from the shackles of time and space to which they’ve been confined since the beginning of time. This sounds very powerful except that you now have billions of people running in millions of different directions. I postulate that what’s missing in our collective journey to self-actualization is a next generation coordination mechanism.

I use the term next generation because coordination mechanisms have been around as long as human societies. Monarchs coordinated the construction of pyramids and cathedrals; governments coordinated the creation of nations and cities; corporations coordinated the design, manufacture, and sale of products. Who will coordinate the creative energies of these billions of people now that they can collaborate across space and time? How will their diverse priorities be aligned? What laws will govern the products produced by citizens of this world’s diverse nations?

I’m not suggesting an Orwellian type mechanism to control the masses. Instead, I’m stating the rather simple fact that few of the things society values today (with the exception of some varieties of arts & letters and products of the remaining lone craftsmen, perhaps) are products of a single individual’s labor. The products we use, the homes we live in, the organizations we work for, and yes, even the children we raise, are all products of teams. Yet, individuals rarely function in teams in the Web 2.0 world. In fact, the Web 2.0 world encourages the free-agent, lone gun, mentality. Creating your own movies, podcasts, publications, and software services are the order of the day. “As long as you expose these things to be ‘mashed up’ or they are collected in a common repository”, goes the common thinking, “we are building communities.”

I submit that when we mash things up, we rarely ever get anything more than mash, mush or some similar m*sh. Coming from a huge fan of Google Maps mashups; I can say that these mashups aren’t getting me any closer to self-actualization. Are the mashups fascinating and fun? Sure. Are they accelerating science, business, society, and self-actualization? Not so much. Acceleration, the type I believe of which Flake speaks, is facilitated by communities of likeminded individuals in pursuit of something greater than the individual. The names in the halls of greatness span the decades: NASA, DARPA, Bell Labs, Xerox PARC, the Manhattan Project. These organizations have achieved the ends which I believe Flake professes. Web 2.0’s Ajax-based maps and digital audio / video are at best standing on the shoulders of giants when compared with such predecessors.

So where does this leave Social Computing and Internet Singularity? Surely there are enough serious challenges that would benefit from a networked team of one billion minds – think global warming and alternative energy, stem cell, DNA, AIDS, and cancer research, space travel and so many more things. With corporations and governments cutting funding for long-term scientific research in favor of short-term profits and political partisanship, respectively, the opportunity is there for someone to fill the shoes of the next generation coordinator.

Can such coordination be done via the Web? How would such projects be funded? How would patents and intellectual property be handled? What aside from money would motivate people to participate in such projects? All these questions and more have yet to be handled in a serious and pragmatic fashion. It’s the answer to these questions and the energy of the visionaries that choose to tackle them, not AJAX and SOA, that will get us all climbing Maslow’s pyramid.

I’m not well-versed in the nuances of NASCAR racing and don’t understand the spectacle very well so when I say this, please take it with a grain of salt. The whole Java versus .NET thing seems to me like a NASCAR race, one car edging ahead of the other and then again giving up ground to the competitor… on and on again for countless monotonous laps. I am in the process of re-immersing myself in the newer releases of Java. It has been years since I dealt with Java on a regular basis – the 1.1 through 1.4 days. This week, I had the chance to see a lightweight EJB 3 container in action, working through Oracle’s slick new IDE with integrated Java Server Faces (JSF) and Object Relational Mapping tool (Toplink, in this case) support. Suffice it to say that I was floored with the progress the Java community had made away from the monolithic J2EE / EJB 2.1 towards the lightweight model espoused by frameworks such as Spring.  Just when it appeared that the Java car was pulling ahead ready to steal the race, along comes the announcement of the Community Technology Preview of ADO.NET vNext. NASCAR fans, we’ve got ourselves a race again. Below I offer a preview of some of the aforementioned technologies:

• Java Server Faces (JSF) – Formally, the implementation of the JSF specification developed under JSR 127 and JSR 252. For those from the .NET world, this is tantamount to custom Web controls. The newer UI’s allow you to drag and drop JSF components onto a pallet and wire up event-based handling to build your user interface layer. As with the newer .NET components, AJAX capabilities are being built into a lot of these components. The Wikipedia writeup for JSF has links to several popular JSF toolkits, many of which offer online demonstrations or reference applications.
• Object Relational Mapping Support – Along with EJB 3 came the Java Persistence API, which codifies various persistence frameworks into a single API. This includes support for new Java 1.5 language features, such as annotations, which are pure Java metadata descriptors that can be used to interact with the persistence framework (e.g. Hibernate) being used. In addition, XML mapping descriptors continue to receive support. Particularly interesting to me was not the support for ORM, which has been an item in the Java developer’s toolbox for years, but the rich integration of the API support in some of the IDEs. I’ve included a screenshot from Oracle’s JBuilder that illustrate the steps in creating Entity Beans from existing database tables. In particular, note the ability to select the type of collection to be used as well as to annotate the collections as either eager or lazy loaded (see Fowler Lazy Load pattern from P of EAA) 
• ADO.NET vNext – This version of ADO.NET, slated to come out after the not-yet-released ADO.NET v3.0, is revolutionary in the minds of those at Microsoft. It’s great to hear the folks at Microsoft talk about impedance mismatch as if they had just discovered it. “With the new version of ADO.NET and LINQ and the powerful capabilities of the Entity Framework …” Y-A-W-N. C’mon guys, you’re just as far behind in the ORM world as the Java community was in the visual design and UI component world 5 years ago. Time to hit the gas and at least catch up. What should be really interesting is to see just how good the IDE support is for their Entity Framework. As you can see from the Oracle screenshot, Microsoft has a lot of catching up to do.
