I'm making it public because I like it. It's a little less formal than most things on my site.) at Dynamicland, I had this idea for an 'audio recorder' or 'audio note' device -- it would be a thing that has a push button, a microphone, and a receipt printer: https://omar.website/posts/notes-from-dynamicland-programming-raspberry-pis/ Fri, 07 Dec 2018 00:00:00 +0000 https://omar.website/posts/notes-from-dynamicland-programming-raspberry-pis/ body { overflow-wrap: break-word; } pre { overflow-wrap: normal; } .statements { max-width: 100%; } .statements img { max-width: 90%; } .pi-image-map div { position: absolute; opacity: 0.5; } .pi-image-map a div:hover { opacity: 0.7; } .pi-image-map div span { position: relative; top: 50%; transform: translateY(-50%); line-height: 0; letter-spacing: -0.4px; color: white; } .pim-big { font: 500 2.7vw 'Helvetica Neue', sans-serif; } .pim-medium { font: 500 1.7vw 'Helvetica Neue', sans-serif; } . https://omar.website/posts/notes-from-dynamicland-geokit/ Mon, 06 Aug 2018 00:00:00 +0000 https://omar.website/posts/notes-from-dynamicland-geokit/ body { overflow-wrap: break-word; } pre { overflow-wrap: normal; } .figure { max-width: 90%; } .figure.dynamicland-page img { max-width: 90%; max-height: 1000px; } .figure.dynamicland-page img { border: 1px solid #ddd; } .figure.tilelayers { max-width: 100%; } .figure.tilelayers img { width: 20%; } .tweet-figure { max-width: 500px; } .figure.chaining img { max-height: 450px; max-width: 30%; } Hey ___, I know you've been curious about some of the stuff I've done at Dynamicland. https://omar.website/posts/pinhole-a-falling-ball-demo/ Thu, 07 Aug 2014 00:00:00 +0000 https://omar.website/posts/pinhole-a-falling-ball-demo/ Hover your mouse over this screenshot to *see into the future* At Hacker School last year (I was part of the winter 2013 batch), I spent a few days making a falling ball game/demo (source on GitHub). I've neglected to write it up and package it until now. It's pretty simple, but it's got one really cool feature that I wanted to show off: you can ~~see into the future~~. https://omar.website/posts/my-favorite-regional-transit-maps/ Fri, 18 Jul 2014 00:00:00 +0000 https://omar.website/posts/my-favorite-regional-transit-maps/ Megaregions of the U.S. (original at America 2050) I've been working on a post about riding local transit from New York City to Boston. While writing, I've run into some really neat regional transit maps, which cover an entire metropolitan area, cluster of metropolitan areas, or region of the United States. They focus on commuter and intercity services, as opposed to metro maps covering local subway and sometimes bus lines. https://omar.website/posts/functional-reactive-twitter-bots/ Tue, 18 Mar 2014 00:00:00 +0000 https://omar.website/posts/functional-reactive-twitter-bots/ The key idea of functional reactive programming (FRP) is time-varying values, which the Elm language calls Signals. In a discrete FRP system like Elm, you can think of a Signal as a stream of individual events. Rather than using a callback function to swing at every event that shows up, we use higher-level operators to manipulate a whole stream of events at once. Signals fit modern "real-time" social data really well---like Twitter feeds. https://omar.website/posts/micropolis-simcity-classic-mac-download-and-build-guide/ Fri, 31 Aug 2012 00:00:00 +0000 https://omar.website/posts/micropolis-simcity-classic-mac-download-and-build-guide/ I’ve made some minor changes to Micropolis, the open-source release of the original SimCity, so that it compiles and runs on Macs (or, at least, on my 10.8 Mac). You can download my build and try it, as long as you have XQuartz. All the other ways to play this game are kind of dumb (until now, the best method for a Mac user to play was to run the Windows version).
