The Best Ever

Well, this one was too long (951 bytes) for category 4 The Old Standby, but was rated The Best Ever by the judges... (I did submit it for Inner Beauty, but hey)

The Perl part need an ANSI term for it use some escape codes for highlighting, and the PostScript part need ghostscript or you friendly neighborhood PS printer.

Please note that whitespace actually holds information. And yes, it is actually PostScript: it ends with showpage...

Excerpt from the SOLUTION file:

This program has a lot to tell. Though Perl and PostScript are very different in appearance (one if infixed, the other postfixed, one works with lists, the other with dictionaries...), in this case they performed quite hand in hand. I must add that PostScript is very well suited for obfuscation even for novices, thanks to the def operator.

If you look closer at the output of these two programs, you will notice that the highlighted part, the one that is missing in the output of the Perl program, is exactly (your screen/eyes/printer resolution may vary) the one that is printed by the PostScript file. Isn't this some complementarity?

[marto]: good morning all

[Corion]: I hope you had a good weekend!
[Discipulus]: good morning again monks!
[choroba]: Good morning!
[Corion]: I have a rough plan to release an ImageNet classifier in Perl (well, using pretrained data, but still a nice toy)
Discipulus is going mad with the new win10 client.. tried mv Cortana /dev/null but no succes
[Corion]: Ouch - another pretrained set is available, using images from IMDB and Wikipedia. So I expect interesting results for non-PR images where people are pictured that are not made up
