  • Early computer aided art and programs I’ve written, dating back decades.

    In the mid 1990s I used ImpulseTracker to create music. The music sucks. But losing the original source .IT files would be heartbreaking.

    Likewise, my first programs, written as a child in MS DOS batch files circa 1991 – basic menu driven interfaces that facilitated launching my installed sharware… I don’t have the games the program points to anymore, but that isn’t the point ;)




  • That reminds me…

    In circa 1995 I was running a dial upBBS service – as a teenager. So if course, it was full of bootlegged video games and such, and people would dial in, download a game, log off.

    Someone uploaded Descent or something like that. But they had put "deltree /y C:" or similar into a batch file, used a BAT2COM converter program, then a COM2EXE program, then padded the file size to approximately the right size with random crap (probably just using APPEND)… And uploaded it. Well, fortunately for the rest of my users, I say the game and said: oh, that’s neat, I should try it and copied it to another computer over my internal network and launched it. It started deleting files right away and I hit CTRL-C to abort. I lost only a few dozen files.

    Banned the user, deleted the package. Got lucky.












  • However, some UA crops (for example, tomatoes) and sites (for example, 25% of individually managed gardens) outperform conventional agriculture. These exceptions suggest that UA practitioners can reduce their climate impacts by cultivating crops that are typically greenhouse-grown or air-freighted, maintaining UA sites for many years, and leveraging circularity (waste as inputs).

    Tomatos it is then ;)

    It’s really hard to compete with the efficiency that economies of scale provide. So this result isn’t unexpected.

    It doesn’t however negate the other positive impacts of urban gardening – in particular, the impacts on the people doing the gardening (everything from psychology, vitamin D, immune system benefits to playing in the dirt, etc.).
