It is getting late, and I am sitting at my desk sorting various bits of data on my hard drive. This the modern form of paper filing, as our grandparents used to do with carbon copies of memos in 1950's office buildings. But we have a new phenomenon - data files that we pull from the internet. Personally, I like to save articles from the New York Times on random subjects. Why? I don't know, I rarely read the article again - if at all. But the habit causes me to sit at my computer and contemplate things with enough substance to pass the time (but not too much to get distracted), waiting for download.
