JStrack is a freeware hurricane tracking program written entirely with Tcl/Tk. 17 October 2010 updates by me (Jim Graham). NOTE: JStrack's author (that's me...Jim, N5IAL) was diagnosed with cancer back in 2006, and has since kicked caner's backside into another universe. I am still dealing with the long-term side effects, but that's enough about that. Thanks to The Kendrick Group, JStrack has a rather large home at jstrack.org. It is also the home of my brewing pages, including a Tcl/Tk based brewer's recipe formulator called GTbrew2. I've also got a few other Tcl/Tk toys, like as 24-hour analog clock, a Sudoku puzzle script that uses two external C programs to generate Sudoku puzzles at various levels, solve either generated or manually input puzzles, etc. JStrack is freeware or, if you prefer, donationware. Here's how it works: if you want to use JStrack, you are free to do so. If you really, really feel that you must send money, please send it to the Red Cross/Red Crescent (depending on where you are), the Salvation Army, or basically, some charity-based disaster relief agency. ---- Links: * PURL: http://www.purl.org/net/jstrack * jstrack.org main page: http://www.jstrack.org (not much of an index there, but it works) * JStrack: http://www.jstrack.org/jstrack/ * Brewing: http://www.jstrack.org/brewing/ * GTbrew2 (Tcl/Tk based brewer's recipe formulator): http://www.jstrack.org/brewing/ * My Sudoku.tcl, extra-simple digital clock, and my 24-hour analog clock are all listed in the "My Tcl/Tk Stuff" section of the main index at http://www.jstrack.org ---- [Category Application] [Category Science]
