Graph of recorded file access and modification times for files in FOI2009.zip
Here's a graph of file access times versus file modification times as recorded in the
FOI2009.zip archive of the cracked CRU files. Note that the graph doesn't cover the entire range of times spanned by the files, but only the more 'active' time periods.
Update 2010-08-20: The old graph image was nicked, so I've replaced it with a new one -- which should give the same information.
Update 2010-09-04: OK, here's the
gnuplotprogram for generating the graph from the semi-processed data:
#!/usr/bin/env gnuplot set terminal postscript color set output "vomit-zip.ps" set title "File Access Times vs. File Modification Times in FOI2009.zip" set xlabel "File modification time (UTC)" set ylabel "File access time (UTC)" set xtics rotate set xdata time set ydata time set ytics 864000 set grid xtics set grid ytics set timefmt "%Y-%m-%d,%H:%M:%S" set format xy "%Y-%m-%d" set xrange ["1988-01-01,00:00:00":"2009-12-01,00:00:00"] set yrange ["2009-09-10,00:00:00":"2009-11-29,00:00:00"] set key box plot "vomit-zip-FOI2009.out.txt" using 4:6 with points pt 7 \ title "FOI2009.zip", \ "vomit-zip-mbh98.out.txt" using 4:6 with points pt 7 \ title "mbh98-osborn.zip in FOI2009.zip"
