    Plumbing Chops 

    In my line of work I am often reminded of this brilliant passage from  Ellen Ullman’s “The Bug” (which I reviewed earlier):

    “Programming starts out like it’s going to be architecture–all black
    lines on white paper, theoretical and abstract and spatial and
    up-in-the-head. Then, right around the time you have to get something
    fucking working, it has this nasty tendency to turn into plumbing.


    It’s more like you’re hired as a plumber to work in an old house
    full of ancient, leaky pipes laid out by some long-gone plumbers who
    were even weirder than you are. Most of the time you spend scratching
    your head and thinking: Why the fuck did they do that?”

    To take the metaphor a little bit further, let me bring up one actual plumbing nightmare that I faced when I was renovating my apartment. One of the contractors clumsily knocked  off a valve on a piece of  water piping that did not have a local shutoff. The only shutoff was in the basement, and required turning off the water for the entire line. And the super, who could do the shutoff  was not in for a couple of days.

    Another contractor knew exactly what to do in that case. He created something that he called a “chop” (I found out later that the term is Ukrainian). It’s a conical piece of wood, shaped like a fat pencil that is hammered into the hole in the pipe. In a couple of minutes the wood swells up and completely plugs the leak. Add some duct tape around it, and you got a very good temporary plug that is almost as strong as the unbroken pipe.  It makes the worst permanent solution (wood rots), but the best temporary one (it can be applied without taking the whole system down and is reasonably strong).

    Chops, or as they are called in English – thru-hull plugs, are a maritime invention: they are used for emergency repairs on boats. These days you can even buy a ready made set.

    People think of software as of something static. Well, dynamic websites are more like a ships out at sea. Sometimes you have to patch them up in a storm. And then a good, strong “chop” is the best you can hope for until you can repair the leak permanently. And you are going to sink unless there’s somebody around who knows how to make a “chop”.

    Cubozoans 

    “Box jellyfish, or cubozoans, are bizarre, highly poisonous predators (New Scientist, 8 November 2003, p 34). “These are fantastic creatures with 24 eyes, four parallel brains and 60 arseholes,” says Dan Nilsson, a vision expert from the University of Lund in Sweden.”

    So, cubozoans is another name for bubble-era web startups.

    The Little Cement Platform 

    I had some of the best times of my life fishing in Odessa. There were two piers (jetties) that I frequented, the I and the L shaped one. 

    I probably fished the most on the I shaped pier. I must have known every little nook and cranny there.

    The L (Russian Г ) shaped pier for some reason had less fish around it, but allowed for fishing even in windy conditions – the water behind it was calm even when the wind was high.

    All the piers were connected by a wave breaker structure, an underwater wall that ran parallel to the shore and about half a meter below the surface. You could walk on it and fish from it. My father would not allow me to wear his waders because I could have drowned in them, so I had to spend many hours fishing from the wave breaker cold, wet, miserable and with feet cut up by mussels.

    In theory you could walk on the wave breaker from the I pier, passing a few more piers and reaching a small cement platform a little bit higher than the L pier (it can barely be seen in the photograph). I never got there because there was a break in the wave breaker somewhere in the middle. I could easily swim over it, but for some reason that break always freaked me out, and I never reached that cement platform, although a lot of people did. 

    A few days ago I had a dream where I was looking at the little platform from the L pier.
