Now, if you like technology, as I do, a System Folder crash of this sort is not an insuperable problem. If you want to reinstall software to recover from a computer disaster at home, and if you have the installers at home, you can reinstall. And if you have the serial numbers recorded at home, you can type them in at the appropriate places when you reinstall, so the reinstallation will work. Unfortunately, I wasn't quite that well prepared, but fortunately I had alternatives at hand -- I powered up another laptop I already had at home, and connected the two laptops together over the tiny wireless LAN I run in my apartment. I pulled software and other installation files over the network from one machine to the other, and in doing so I may be said to have violated the installation process that (to invoke the language of the Digital Milllennium Copyright Act) "controls my access" to the technology, to the copyrighted work. Technically, perhaps, I had violated the Digital Millennium Copyright. Please let's not let the news of my transgression leave this room.
