@edsu I jumped on HTML 4 as soon as possible and used to use James Clark’s nsgmls to make sure everything was validated, so I would trip over as few rendering quirks as possible. I also have some #retrocomputing books that will stay with me (some pictured). The ZX Spectrum was my first computer, Foley and Van Dam was comprehensive, writing a #PostScript interpreter on Apollo workstations was my final year project, and I still love the #Z80.
