    Perfect Workmanship 

    Perfect workmanship is expensive. Why? Because it means starting over or laboriously fixing tiny little imperfections. Joel Spolsky describes this very nicely in his article about craftsmanship:

    “The moral of the story is sometimes fixing a 1% defect takes 500% effort. This is not unique to software, no sirree, now that I’m managing all these construction projects I can tell you that. Last week, finally, our contractor finally put the finishing touches on the new Fog Creek offices. This consisted of installing shiny blue acrylic on the front doors, surrounded by aluminium trim with a screw every 20 cm. If you look closely at the picture, the aluminium trim goes all the way around each door. Where the doors meet, there are two pieces of vertical trim right next to each other. You can’t tell this from the picture, but the screws in the middle strips are almost but not exactly lined up. They are, maybe, 2 millimeters off. The carpenter working on this measured carefully, but he was installing the trim while the doors were on the ground, not mounted in place, and when the doors were mounted, “oops,” it became clear that the screws were not exactly lined up.”

    I was recently reading a book by Tracy Kidder called “House”. It’s a great book by the same Tracy Kidder who wrote “The Soul of a New Machine”. “The Soul” is a book about computer architects and builders. “House” is about their counterparts in the business of building houses. In one book Kidder describes the extremely stressful process of designing and building an Eclipse MV/8000 minicomputer. In the other he describes the similarly stressful process of designing and building a Greek Revival house.

    Both books read like a work of fiction, but they are absolutely factual, written about real people and real products. It’s very strange to be able to go and look up characters that became so familiar thanks to those two books. Steve Wallach from “The Soul” went on to form his own company, Convex Computer, sold it to HP in 1995 and is now a venture capitalist. You can even look up what he looks like now.

    Bill Rawn from “The House” heads a big architectural firm of his own. Going there and seeing the buildings that he’s built after the house in the book is somewhat strange: he feels like a literary character, yet there he is, many years later after the events of the book took place. Souweine House, Amherst, MA is listed in the awards section of the website, but unfortunately there is no photo of it.

    Interesting to note that while the Eclipse minicomputers are probably worthless now, the Souvweine House must be worth a tidy sum of money.

    While building the Souweine house, the builders made a mistake concerning the frieze, an important architectural element. They go on to fix it, but in order to do it perfectly, they’d have to rip everything out and start anew, which is just like in Joel’s door trim case is prohibitively expensive.

    “Jonathan feels sorry for the trouble the frieze caused, but not for the little imperfection it represents. No one else will see it, but Bill has said that even when repaired, the frieze won’t quite reproduce his intentions. Orthodox Jews have a tradition that until the Temple in Jerusalem is rebuilt, they will not erect a house or a building without giving it one deliberate imperfection. Though not a member of the Orhodox branch of Judaism, Johnathan believes in the inevitability of imperfection. So why not celebrate it? “There’s a flaw in the house …,” he says, and flashes a smile, a shooting star of a smile, “… which the pernicious part of me sort of likes.””

    By the way, I can’t pass up mentioning my favorite, but apparetly later edited out, quote about Kidder. “For a woman, Tracy really know her stuff and gets into a great amount of hardware detail”. What do you think the source for it is?

    Kissed by a Train 

    A train conductor announced some words of wisdom today: “Don’t push a stroller into a closing train door”.

    Train doors in NYC subway cars close with a tremendous amount of force and don’t have a sensor that would keep them open if somebody got stuck. You are at the mercy of a conductor, who usually rapidly opens and closes the door, hitting you a couple of times more before you can enter the car. Jumping into closing train doors is a main event in NYC Olympics though.

    You can easily recognize a person “kissed” by a subway door – the rubber “lips” leave black marks on skin and clothes.

    It’s interesting to note that the announcement probably was made because somebody actually tried to do this with a baby carriage. That’s Darwin Award material.
