have you ever noticed some jpgs have crap appended to them?
i mean the bytewise contents, not the visual appearance
so, ive been going thru my mpl studios shit, trying to find bigger copies of the promo's i have collected over the years, and having decent success at it
i noticed that the production copies frequently have 51 extra bytes after the 0xffd9 "end of scan" marker that the jfif standard mandates
most software ignores the extra data, but i wrote some code that tells me if there is junk at end of file -- not rocket science, not crucial, but at one time i thought maybe it was the cause of a certain bug i was experiencing with a rendering library (it wasnt)
and actually i see this scenario kind of a lot, not just with mpl
usually it is not any great amount of extraneous data
usually it is uninteresting html code
most of the time i dont bother to look at it
but today i wondered, "why am i seeing so many mpl files with 51 extra bytes?"
so i actually looked at the data (shout out to mirkes.de Tiny Hexer) and it was what looked like an IP address followed by definitely a timestamp
copied and pasted the IP into firefox and what did i get?
a promo page for Paul Markham
dunno what to make of that, except i doubt it's a coincidence
but i never thought of PM as being the artsy type
