Igor, this is magnificent. All it needs is a generator script to select language X and language Y, or database X and database Y and then autopost to Hacker News.
I'm doubtful that Hacker News would tolerate autoposts. But it would make for an excellent "Show HN" sideproject that somebody can make to boost their coding skills.
Yeah, [spoiler] killed the applicability of this where I couldn't cut and paste it here during the language fights. Yet, I bust out laughing seeing [spoiler]. That was just too funny. Especially "corroboration" that followed.
Interestingly, I really liked [spoiler] too, but I also hoped that this blog post could be reused in future language fights (and it is a shame that [spoiler] could prevent that). Potentially a revised version of this blog post could be helpful.
