The highs and lows of former-Borland's Dumbledore
Magic of application factories
You'd be hard pressed to find anyone in the software tools business who has seen more changes in programming than David Intersimone. Not all of them welcome.
Best known as "David I," he worked for more than two decades at Borland Software, the company regarded by many as having invented the integrated development environment (IDE). At Borland, Intersimone held positions as director of research and development for languages and tools covering Windows and Java.
Next he became vice president of developer relations and chief evangelist at Borland's subsidiary, CodeGear, where he was responsible for an online developer community of more than six million codederos. And as of last week  Intersimone officially became an employee of Embarcadero Technologies.
A self-described "code junkie," he's widely known as a champion of software developers, and frequently referred to in industry rags as an icon. "It's the beard," Intersimone told The Reg recently. And, sure, that beard may make him look the headmaster at Hogwarts , but Intersimone is all about programming in the real world.
"The thing I think about most of the time is how we can provide developer environments and tools that can do a lot of things very simply and easily, but that don't keep you from all the power, all the expressiveness - all the craziness - you need to build something wonderful," he said.
Intersimone: minds his languages
It's probably his belief in building "something wonderful" that's helped keep Intersimone going. Borland not only paid the price for taking on the giant Microsoft but its flag-carrying tools business was crushed by shifting industry tectonics before being unwanted by its own management.
During his twenty-five-year tenure at Borland the company established a firm - if distant - number-two position behind Microsoft on Windows tools thanks to its Turbo Pascal and Delphi tools offering Rapid Application Development (RAD). Borland then jumped on some new fangled thing called Java last decade, creating one of the industry's most consistently popular Java IDEs - JBuilder.
Microsoft strikes back
Microsoft, though, is not known for letting competitors get too uppity, especially not last decade when it played dirty against Netscape. Microsoft went under cover and Intersimone saw a number of his colleagues lured away to become employees of Microsoft. These included Anders Hejlsberg , a principal engineer of Turbo Pascal and Delphi chief architect. Hejlsberg went on to create Microsoft's object-oriented language offering C#. Such was the brain drain, Borland took Microsoft to court  in an attempt to see it off.
By the start of 2006, the juggernaut Borland faced was no longer Microsoft. It was the open-source Eclipse that had effectively flattened the IDE market. Such was the pressure Eclipse exerted on licensing and innovation from tools vendors like Borland that even this company, with its hugely popular JBuilder and technology heritage, was looking to get out of the game by spinning out its IDE products as a separate business.
After eight months, nobody was biting and Borland reluctantly retained its IDE tools. Not that it was happy, and the business was still up for sale. Then came along Embarcadero, which this year purchased Borland's IDE business - which included JBuilder and a reinvented version of its venerable Turbo line called Developer Studio, plus several of the company's star employees including Intersimone.
Rather than roll over and die as a lesser mortal might throughout this, Intersimone came to see the frameworks emerging from Eclipse - that ultimately helped unseat him from Borland - as "leveragable resources."
"The early versions of Eclipse weren't that good," he recalled, "and we originally saw it as a competing product. But after a couple of years of conversation inside Borland - and with the release of Eclipse 3, with its clean plug-in architecture - we had that 'ah-ha' moment. Here was this set of general purpose, open-source frameworks that actually freed us to focus our efforts on value built on top."
JBuilder 2007 was the first version of the IDE built on the Eclipse framework, in 2006.
While Eclipse was creating a forced paradigm shift among software development toolmakers, Intersimone was considering a shift in the development paradigm itself.
"In the early days, programming was just about the languages, high-speed compilers, and debuggers," he said. "Then it was about the frameworks - the ObjectWindows and MFC [Microsoft Foundation Class] libraries, user-interface frameworks, database frameworks. Then it was components. Now it's application modules and higher levels of abstractions, not just in fundamental data types and operating system components, but applications as well."
And that leads to what Intersimone calls "application-driven development." This model, he explained, pulls the structure, evolution, and logic behind developing an application into the application itself. The result is reusable software modules that capture the intent of the coder in annotated templates or "cheat sheets" that stay with the architecture of the applications.
Intersimone calls these code-plus-metadata modules "application factories."
Application factories debuted in JBuilder 2008 , released in April.
"Say you need to build a shopping cart, or an ecommerce system, or an ERP system," Intersimone said. "All of those things have been built before, so if the tooling can help make that code into a reusable module - into an app factory - then you don't have to think about the infrastructure. All you have to think about is the kind of application you need to build. People do this all the time in consulting gigs, or in the large system integrators. If they build a financial system for one bank, they build it for a hundred banks."
"We think of that as tooling, not for the IDE, but for the application," Intersimone said. "In application factories, the programmers can do tooling for their applications, so they can provide simpler interfaces for making changes at the application level and to the application code."
The metadata captured in application factories would also help with the maintenance of existing applications, Intersimone said. "The everyday things that can be captured by the person who is producing these modules can free other developers from wasting time finding all the places where they have to make changes, or figuring out what the person did the last time they touched an application."
Unfortunately for Intersimone's optimism and enthusiasm, CodeGear's lack of resources showed  and JBuilder 2008 was rough around the edges.
Once again, with feeling
Intersimone appears to believe things will be different under the new owner, Embarcadero. His blog makes repeated references  to the company's combined staff of 500 and revenues of $100m, which could help to build and deliver more innovation and more polish than the unwanted CodeGear child of Borland was able to achieve.
And, as with the old days of Borland when Microsoft was the main competitor on Windows, the ethos remains as ever: platform independence. This time, it's independence at the database layer. Also, there's the continued belief in vendors adding innovation on top of open source frameworks, rather than leaving it up to the community to come up with something wonderful on its own.
"Some people would tell you that tools don't matter. That open source or the platform and stack vendors will solve every problem and satisfy every pain point," Intersimone blogged after we spoke to him.
"Today, software is no more reliable, no more predictable than it was before. We need to build better applications, faster, and with higher reliability. Our economy needs every designer, architect, developer, and administrator to be performing at the top of their game".®
