I thought I could follow at least some of the unobsfucated C, and then this monstrosity: t = "++#m--%am*@R<^1c/@%[_[H3c%@%[_[[email protected]#d-@%:_^BKd<<Z/03e>>`/03e<=0f>=/f<@.f>@1f==&g!=\'g&&k||#l&@.BCh^@.BSi|@.B+j~@/%Yd!@&d*@b"; Could someone please explain what is going on in that routine?

Every other month an amazing project from Fabrice Bellard comes back under the spotlight on HN. I guess you could train a ML model on previous posts and make a automatic karma-generating machine :-)
