Being an "HP family", my dad bought me an HP 49g+ calculator with RPN. I loved that thing. Going against the grain and doing things differently is very important to me. Here I had to get special permission from school to use this device because it was not the approved crappy TI calculator. Luckily I had a really cool maths teacher (hello Mr. Pieke!) and he made it happen.\u003C\u002Fp>\n\u003Cp>I loved RPN and stack-based programming. I created all kinds of small programs in User RPL. On holidays I would be programming stuff in my tent. On hpcalc.org I downloaded all kinds of knowledge bases for e.g. the periodic table and loved reading things from the calculator. The calculator broke down at some point, then I bought a 49g+, but that was stolen from my student room later. I still miss it.\u003C\u002Fp>\n\u003Cp>\u003Cstrong>next\u003C\u002Fstrong>: \u003Ca href=\"\u002F2024\u002F06\u002Fdat-narrenschip\u002F\">2005 - Dat Narrenschip\u003C\u002Fa>\u003C\u002Fp>\n\u003Cp>\u003Cstrong>previous\u003C\u002Fstrong>: \u003Ca href=\"\u002F2022\u002F10\u002Freverse-engineering-binary-format-of-hp\u002F\">1999 - Reverse engineering the binary format of HP ChemStation\u003C\u002Fa>\u003C\u002Fp>\n",[],{"title":17,"path":18},"[TSTIL] Social Gravity","\u002F2022\u002F10\u002Fsocial-gravity\u002F",{"title":20,"path":21},"[TSTIL] SnelTrein","\u002F2022\u002F10\u002Fsneltrein\u002F",[23,28,33,36,40,43,46,50],{"title":24,"path":25,"note":26,"series":27},"Mapping out Dark Code","\u002F2026\u002F03\u002Fmapping-out-dark-code\u002F","2026",false,{"title":29,"path":30,"note":31,"series":32},"The software that I love","\u002F2022\u002F10\u002Fthe-software-that-i-love\u002F","Series · 36 posts",true,{"title":34,"path":35,"note":26,"series":27},"Navigating the Fog of War: Age of Empires, AI Agents, and the Rise of Dark Code","\u002F2026\u002F05\u002Fnavigating-fog-of-war-age-of-empires-ai\u002F",{"title":37,"path":38,"note":39,"series":27},"The Future of Programming Systems - four thoughts","\u002F2024\u002F09\u002Fthe-future-of-programming-systems-four\u002F","2024",{"title":41,"path":42,"note":39,"series":27},"Always Optimize the Feedback Loop","\u002F2024\u002F07\u002Falways-optimize-feedback-loop\u002F",{"title":44,"path":45,"note":39,"series":27},"\"Security Is Our Top Priority\" is BS","\u002F2024\u002F07\u002Fsecurity-is-our-top-priority-is-bs\u002F",{"title":47,"path":48,"note":49,"series":27},"10x teams","\u002F2025\u002F02\u002F10x-teams\u002F","2025",{"title":51,"path":52,"note":49,"series":27},"Hiring, from the Other Side","\u002F2025\u002F10\u002Fhiring-from-other-side\u002F",1792876808996]
