So I wrote my own \u2014 an HTML5 web app inspired by gamedesign.jp&#8217;s &#8220;Card&#8221; game, playable online, with an Android version in the Play Store. The randomness keeps it honest; the solver keeps it interesting.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Lollipop<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Lollipop<\/strong> is my favorite kind of software: invented together with my son. We came up with a paint-by-numbers game where the numbers can only be obtained by doing calculations \u2014 and it quietly boosted his addition, subtraction and multiplication skills into the thousands range. Creating the puzzles by hand cost real time, so naturally I wrote a generator that produces an SVG &#8220;Lollipop&#8221; for any desired word.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Ports and bridges<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The Minesweeper game logic from the mini-games era was ported to JavaScript with Smart Mobile Studio, and a lot of supporting work happened around this bridge between worlds: <a href=\"https:\/\/github.com\/CWBudde\/Pascal-HTML5-Canvas\" target=\"_blank\" rel=\"noopener\">a Pascal implementation of the HTML5 canvas<\/a>, <a href=\"https:\/\/github.com\/CWBudde\/ts2pas\" target=\"_blank\" rel=\"noopener\">ts2pas<\/a> for converting TypeScript definition files into Object Pascal headers, and JavaScript ports of my SOFA and HDF file libraries (<a href=\"https:\/\/github.com\/CWBudde\/WebSofa\" target=\"_blank\" rel=\"noopener\">WebSofa<\/a>, <a href=\"https:\/\/github.com\/CWBudde\/WebHdf\" target=\"_blank\" rel=\"noopener\">WebHdf<\/a>).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Looking back, this era was the hinge: the moment web technology entered my toolbox and never left. The frontends I build today are TypeScript and React \u2014 but they stand on a bridge built from Pascal.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>At some point the browser became too capable to ignore.
