Do You See a Pattern?

I really enjoyed "A Pattern Language, " even though it wasn't relevant to my life other than its influence on the Design Patterns people.

  Gosh, if you've ever even thought about building your own home, APL is invaluable. I think the book should be required reading for everyone in high school, and the language acquired with enough fluency that you could "speak" your own house into being. Fantastic stuff. His magnum opus (4 volumes) The Nature of Order is rather daunting, by comparison, but probably quite important. I've got it, but haven't had time to really dig in...

  I never would have been aware of APL without being in software, and I'd never read anything on architecture or building before that. It was one of the most interesting books I've ever read, and it made a lot of sense. Yes, if I were building my own home, I would definitely re-read it cover to cover.

> The theories that are taught in architecture schools today are of a different sort, and in the belief that the field of architecture should be grounded in intellectual speculation, rather than pragmatic observation, students are more likely to be assigned French post-structuralist texts than A Pattern Language. Which is a shame. It's just astonishing, decades after Jane Jacobs' The Death and Life of Great American Cities, that pragmatic observation is still on the margins. What, a half-century of abject failure in building and neighbourhood design isn't enough to demonstrate the fundamental wrongheadedness of dogmatic, a priori design principles?

  Would you advocate the same change in Computer Science education? Enough intellectual speculation: Java schools for all. To make progress, you have to try something new.

  It's a political problem; the democratization of principles. Sometimes what everyone likes isn't what's best for everyone. It's interesting to note that Kent Beck, who brought Alexander to the attention of Erich Gamma, did so with the intention that it could be used for interface design (if I remember right).

  There's an unforeseen problem with well patterned livable houses--they often don't sell well to conventional real estate buyers. If you need to relocate or access equity quickly, you're stuck with an remarkable property but buyers looking for McMansions. Buyers that do drop by out of curiosity comment with gems such as, "We could never live here, the master bath needs to be as big as the bedroom." Seems as though the only way to move such a property is to offer it so far below market that people become willing to compromise and consider the more livable home instead of yet another generic "keeping up with the Joneses" colonial: http://images.google.com/images?q=colonial%20house http://images.google.com/images?q=colonial%20house (exteriors) It's galling, because such easily substitutable boxes have little intrinsic value beyond market. The cost to build a colonial is quite low compared to the cost of building, for example, "... varying ceiling heights between large and small rooms to create different degrees of intimacy." One eye-line in my home reveals 8 ceiling heights, correlating to the intimacy of the spaces below them. It's extraordinary, but generic buyers want five bedrooms with full baths so what should be livable spaces end up the size of closets. What's worse, when buyers today see the prices of McMansions plunging, they expect to see the price of a well patterned home (that may have cost 5x - 8x as much to build) also plunge, despite the more complex home already having a replacement cost higher than its asking price, price of materials and labor having risen. (PS. Serious inquiries welcome for a well patterned home a commuter train ride from Manhattan.)

I recommend Notes on the Synthesis of Form to everyone. For one, it's a delightful read (Alexander is a master linguist), but it's also tremendously helpful for anyone thinking about building a large system, especially software. The main takeaway for me was thinking in terms of systems of constraints. When designing a vacuum, constraints might be: needs to be reasonably priced, needs to be profitable, needs to be easy to carry, needs to be durable, needs to be powerful enough, etc. Adjusting one constraint usually affects another, so it's easy to see how complicated this can get. Alexander formalizes the process, and demonstrates mathematics to solve the constraint problem. This assumes, of course, that you can articulate and quantify the constraints in the first place. Web developers are lucky: unlike architects or product designers they can quickly test their assumptions (A/B tests) and move the system to a better state.
- bengebre 17y ago
  I second the recommendation. A Pattern Language outlined a lot of the actual patterns (which was neat), but Notes on the Synthesis of Form did a better job of illuminating a broad conceptual foundation for designing systems. I think I need to re-read it now that you mention it.
- mbrubeck 17y ago
  I'd also recommend The Timeless Way of Building, which provides the overview of Alexander's method (of which A Pattern Language is just one piece). I once wrote a review of The Timeless Way from a programmer's perspective: http://advogato.org/person/mbrubeck/diary/106.html http://advogato.org/person/mbrubeck/diary/106.html (The Oregon Experiment, which I mention in that link, might also be of interest to programmers inside huge organizations.)

Christopher Alexander also wrote the introduction to Patterns of Software (http://www.amazon.com/Patterns-Software-Tales-Community/dp/0195121236 http://www.amazon.com/Patterns-Software-Tales-Community/dp/0...). It's a great book, and I've unfortunately only had the time to read a few of the essays. It's available online as a PDF from http://www.dreamsongs.org/Files/PatternsOfSoftware.pdf http://www.dreamsongs.org/Files/PatternsOfSoftware.pdf.

I have great respect for Alexander's ideas, but when he's mentioned, I can't resist sharing this cheeky presentation from one of his Berkeley hills neighbors about the "patterns" evident from the exterior of Alexander's house: http://metatime.blogspot.com/2005/04/patterns-good-and-bad.html http://metatime.blogspot.com/2005/04/patterns-good-and-bad.h... (I don't believe the presentation was prepared with the intent to belittle Alexander's work, and I don't share it in a negative spirit -- but rather as a sort of "only human"/"cobbler's children" observation about the contrasts between a professional oeuvre and personal life.)
- UncleOxidant 17y ago
  Wow...that's... really... his house? What a mess. I can't see how a renowned architect would want to live in such a ramshackle way. Seems like if you're an architect you need to have your house be a showcase of your work - an example that clients could look to get an idea of some of your better work.

  That's exactly how I'd expect Christopher Alexander's house to look. The buildings he praises in his work include few cathedrals, and many folk houses in traditional villages around the world. He wrote that the clean, sterile lines of Modernism were designed to enhance the egos of architects, not the lives of their clients. The houses he built in Mexico (The Production of Houses) were made cheaply, using community labor, from handmade local materials. He also believes that a building is never finished, and should be continually modified by its inhabitants. (Stewart Brand's How Buildings Learn is another book that should be read by both programmers and architects.)
