Only started with Perl4 and Perl5 in 1995. I was doing AWK etc for 12 years before that, and resisted switching. I've been doing OO since before C++ hit bigtime, with Objective-C and SmallTalk, so I really like the (no longer new) Perl5 OO style; and the Lispish Map style is also an old friend. What do I hack with Perl? All data that passes my way; systems monitoring scripts at $DayJob, weather data at night, and I cheat on NPR word puzzles. Member: [] [] /. LinkedIn []

N1VUX is my FCC-issued ham radio callsign.

Physicists detect the undetectable: 'baby' solitary waves

«When University at Buffalo theorist Surajit Sen published his prediction that solitary waves, tight bundles of energy that travel without dispersing, could break into smaller, "baby" or secondary solitary waves, experts in the field acclaimed it as a fine piece of work. They also felt that these waves might never be seen experimentally. But Sen and his colleagues have done just that. »

- Solitary waves or Solitons were discovered by John Scott Russell in the Victorian canals in 1834. They've been used for modelling littoral waves and tsuanmi, as well as studied in electromagnet waves and by this author in particulate waves.
