filter rails log to count requests sliced in seconds

Commandline perl filter for, using a production.log from a rails app, display on realtime the count of requests grouped by "seconds to complete" (gross round, but fair enough for an oneliner) :)

cat a bunch of small files with file indication

If you have a bunch of small files that you want to cat to read, you can cat each alone (boring); do a cat *, and you won't see what line is for what file, or do a grep . *. "." will match any string and grep in multifile mode will place a $filename: before each matched line. It works recursively too!!

Create a booklet ps file out of a normal ps (A4 Size)

'booklet' is the name they'll give it in fineprint windows alternative. It's a postscript file prepared to be printed dual side, one page per sheet, and, once finished you can place staples in the middle of the print, fold, and read it like a book.
