    The Plywood-Armored Tractor Tank 

    Software developers often complain about their tools and their co-workers (sometimes the co-workers are tools). I complain as much as everybody (and maybe more), but I always keep in mind Donald Rumsfeld’s famously insensitive quote “You go to war with the army you have—not the army you might want or wish to have at a later time“.

    There’s a pretty gross Russian idiom “to mould a bullet out of shit”, meaning that you can make something amazing out of the worst materials possible. In one of my favorite sci-fi stories, “Microcosmic God“, a biochemist creates artificial life, a race of intelligent microscopic beings called neoterics. In an effort to create stronger metal, he gradually lowers the ceiling of neoterics’ tank, while leaving them only weak metals. The tiny beings proceeded to create super-strong alloys and stop the ceiling’s downward motion.

    Also, here’s a wartime story you might find inspirational. My hometown of Odessa is one of the few Soviet City Heroes — a status that was given to a few cities for particularly valiant defense in WWII.

    Odessa indeed had it tough, facing superior Romanian forces. The inhabitants fought bravely, but were forced to withdraw. Those left behind (like one set of my great-grand parents who did not want to leave their hat store behind) were abused and often disappeared – the Romaninans were particularly pissed. There are many walls in the city riddled with bullet holes right at the chest level.

    One particular weakness of Odessa, a port city, was the lack of tanks. Aviation being relatively weak at the beginning of the war, tanks were the only thing that could stop superior numbers of infantry.

    People of Odessa are known for their quick wit. One solution that allowed for orderly and timely withdrawal was the NI-1 (НИ-1) tank, an elegant psychological warfare weapon.

    NI was simply a tractor with bolted on “armor” made out of low grade thin steel and, as some say, plywood. They had a futuristic look, and in some cases small caliber canons sitting inside much thicker pipes. An attack of a number of these “tanks” turned back the tide of Romanian infantry, which fled in a panic. This is how the tank got its name – NI stands for “Na Ispug” or “For Fear”.

    There are several of these tanks kept as monuments, but some say that these are later recreations, and not the original NI tanks.

    While not as capable as the Killdozer, it was better than New Zeland’s Bob Semple tank.

    Dead Programmer On Coffee 

    often tells me that I should move to Seattle. But there is one reason why I would actually want to move there. And that reason is Espresso Vivace.

    You see, this dude Schomer served in the Army as a metrologist. No, not a meteorologist. A metrologist, a person who measures stuff for a living. When he became a civilian again he decided to apply some of his skills to making espresso.

    Good espresso is very hard to make. It’s no secret, really. And it’s rather well known what you need to do to make good espresso. To oversimplify things you need:

    a) very fresh, properly roasted high quality coffee beans
    b) pure water with a certain degree of hardness
    c) a good quality burr grinder with very fine grind adjustment
    d) a La Marzocco espresso maker with perfectly adjusted for water temperature and pressure
    e) a perfectly fitted espresso tamper (such as one made by Reg Barber)
    f) a thick walled ceramic cup
    and
    g) a barrista who knows what he or she is doing.

    Now, the barrista must be able to do the following things:
    a) correctly adjust the grinder and grind enough beans for one shot. This is a tricky trial and error process – the grinder must be adjusted depending on ambient temperature and humidity.
    b) fill the portafilter very evenly with the correct amount of coffee grinds and tamp them down with enough force
    d) make sure that the group doesn’t have enough time to cool down
    e) place the group into the machine and press the brew button, shutting it off after a correct period of time
    f) judge the quality of the resulting espresso shot and throw it out and make a new one if it’s no good
    g) keep the machine in immaculate state of cleanliness

    All of these steps are important. David Schomer came up with a way to measure and reduce already small temperature fluctuations in La Marzocco machines. He also added extra cooling fans to his grinders to prevent coffee from heating up when ground. He custom made ergonomic perfectly fitted tampers. He measured, modified hardware and technique and then measured again, sharing his secrets with the world.

    Right now I am between espresso machines. When my last machine gave up the ghost (word to the wise, don’t buy any consumer grade Nuova Simonelli machines. If they die, you won’t be able to get any service for them) I decided to get nothing other than a used single group La Marzocco. I can’t afford a new one as it costs around 6 grand, but used ones can be had for as little as $1000. One of the problems is of course that it uses 220V electricity, but I’d be willing to pay an electrician to install a 220V outlet for me. Of course some lucky bustard got an experimental 110V machine, but no such luck for me. Besides, I want the real thing. I am horribly tempted to get an ECM Giotto machine that comes recommended by Schomer himself though…

    Nah, I don’t want to leave New York just because there no good espresso places here. It’s cheaper just to make my own. Or even one day I might open the real Dead Programmer’s Cafe here. Maybe if I find a partner..

    This all kind of reminds me – I am all out of coffee beens. Time to order some more.
