How does it do that, and what lessons can I learn? Mainly I wanted to know how the scheduler decides each task\u2019s priority and how long it\u2019ll take. That week errands, naps, and doomscrolling crowded my time, but I fit in a few interesting chatbot conversations to collect some ideas on the connections, especially <a href=\"https:\/\/claude.ai\/share\/6c20c37a-a334-47a0-883c-8e051a5ecbda\">this one with Claude<\/a>. My prompts were based on some intro articles I found (&#8220;<a href=\"https:\/\/www.geeksforgeeks.org\/introduction-of-process-management\/\">Introduction of Process Management<\/a>&#8220;, &#8220;<a href=\"https:\/\/www.geeksforgeeks.org\/cpu-scheduling-in-operating-systems\/\">CPU Scheduling in Operating Systems<\/a>&#8220;). Researching the terms they brought up directed me to <em>Operating Systems: Three Easy Pieces<\/em> (<a href=\"https:\/\/pages.cs.wisc.edu\/~remzi\/OSTEP\/\">free on the book\u2019s website<\/a>), so I\u2019m going to read it to dive deeper.<\/p>\n<p>But that\u2019s all a side note. My main task is still to add Eisenhower Matrix prioritizing to my Notion system.<\/p>\n<h2>Spirituality<\/h2>\n<p>\ud83e\uddd0<\/p>\n<p><strong>Scot McKnight\u2019s <em>Fasting<\/em> gave me a new perspective for wading back into this spiritual discipline.<\/strong> Fasting is on my radar because studying discipleship has me thinking about the spiritual disciplines, and this is one I\u2019ve mostly avoided because I\u2019m not great at handling hunger. A friend brought up fasting a few weeks ago as helpful training in self-control, and since Lent was starting soon, I decided this would be a good time to look into it again.<\/p>\n<p>McKnight characterizes fasting as a response to a grievous sacred moment, a part of one\u2019s full-body expression of the gravity of a crisis or loss. He contrasts this with an instrumental view where we fast to get something out of it. But here he\u2019s talking about short-term benefits, like answers to prayer or weight loss, because he does see a long-term benefit in the form of body discipline, where our character is shaped by this moderate voluntary hardship.<\/p>\n<p>My plan is to try a small amount of fasting for Lent, skipping a meal on Fridays, to see what happens. I\u2019ve done a few fasts at random times in years past, but this will be a more organized and principled attempt. I want to spend that meal time trying to pray, an activity I don\u2019t excel at but that seems a natural partner to fasting. Mainly I don\u2019t want to get distracted by my usual activities while I\u2019m not eating and forget the reasons I\u2019m doing it.<\/p>\n<h2>Nature<\/h2>\n<p>\ud83e\udd14<\/p>\n<p><strong>I returned to my outside walks thanks to the less frigid weather, and they got a little strange.<\/strong><\/p>\n<blockquote class=\"instagram-media\" style=\"background: #FFF; border: 0; border-radius: 3px; box-shadow: 0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width: 540px; min-width: 326px; padding: 0; width: calc(100% - 2px);\" data-instgrm-captioned=\"\" data-instgrm-permalink=\"https:\/\/www.instagram.com\/p\/DHSpBZ8uae-\/?utm_source=ig_embed&amp;utm_campaign=loading\" data-instgrm-version=\"14\">\n<div style=\"padding: 16px;\">\n<p>&nbsp;<\/p>\n<div style=\"display: flex; flex-direction: row; align-items: center;\">\n<div style=\"background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 40px; margin-right: 14px; width: 40px;\"><\/div>\n<div style=\"display: flex; flex-direction: column; flex-grow: 1; justify-content: center;\">\n<div style=\"background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 100px;\"><\/div>\n<div style=\"background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 60px;\"><\/div>\n<\/div>\n<\/div>\n<div style=\"padding: 19% 0;\"><\/div>\n<div style=\"display: block; height: 50px; margin: 0 auto 12px; width: 50px;\"><\/div>\n<div style=\"padding-top: 8px;\">\n<div style=\"color: #3897f0; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: 550; line-height: 18px;\">View this post on Instagram<\/div>\n<\/div>\n<div style=\"padding: 12.5% 0;\"><\/div>\n<div style=\"display: flex; flex-direction: row; margin-bottom: 14px; align-items: center;\">\n<div>\n<div style=\"background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(0px) translateY(7px);\"><\/div>\n<div style=\"background-color: #f4f4f4; height: 12.5px; transform: rotate(-45deg) translateX(3px) translateY(1px); width: 12.5px; flex-grow: 0; margin-right: 14px; margin-left: 2px;\"><\/div>\n<div style=\"background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(9px) translateY(-18px);\"><\/div>\n<\/div>\n<div style=\"margin-left: 8px;\">\n<div style=\"background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 20px; width: 20px;\"><\/div>\n<div style=\"width: 0; height: 0; border-top: 2px solid transparent; border-left: 6px solid #f4f4f4; border-bottom: 2px solid transparent; transform: translateX(16px) translateY(-4px) rotate(30deg);\"><\/div>\n<\/div>\n<div style=\"margin-left: auto;\">\n<div style=\"width: 0px; border-top: 8px solid #F4F4F4; border-right: 8px solid transparent; transform: translateY(16px);\"><\/div>\n<div style=\"background-color: #f4f4f4; flex-grow: 0; height: 12px; width: 16px; transform: translateY(-4px);\"><\/div>\n<div style=\"width: 0; height: 0; border-top: 8px solid #F4F4F4; border-left: 8px solid transparent; transform: translateY(-4px) translateX(8px);\"><\/div>\n<\/div>\n<\/div>\n<div style=\"display: flex; flex-direction: column; flex-grow: 1; justify-content: center; margin-bottom: 24px;\">\n<div style=\"background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 224px;\"><\/div>\n<div style=\"background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 144px;\"><\/div>\n<\/div>\n<p>&nbsp;<\/p>\n<p style=\"color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; line-height: 17px; margin-bottom: 0; margin-top: 8px; overflow: hidden; padding: 8px 0 7px; text-align: center; text-overflow: ellipsis; white-space: nowrap;\"><a style=\"color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: normal; line-height: 17px; text-decoration: none;\" href=\"https:\/\/www.instagram.com\/p\/DHSpBZ8uae-\/?utm_source=ig_embed&amp;utm_campaign=loading\" target=\"_blank\" rel=\"noopener\">A post shared by Andy Culbertson (@thinkulum)<\/a><\/p>\n<\/div>\n<\/blockquote>\n<p><script async src=\"\/\/www.instagram.com\/embed.js\"><\/script><\/p>\n<h2>Geography<\/h2>\n<p>\ud83d\ude42<\/p>\n<p><strong>I chose some map projections for learning world geography.<\/strong> I don\u2019t know when I\u2019ll actually learn it, but the motivation comes up pretty regularly now. Of course, the trouble with world geography is it takes place on a globe, which gets distorted when you flatten the surface onto a screen or a page. If I want to learn by drawing, I\u2019ll need a flat view of the land. I looked through Wikipedia\u2019s <a href=\"https:\/\/en.wikipedia.org\/wiki\/List_of_map_projections\">list of map projections<\/a> and ended up with three winners that I\u2019d use for different purposes:<\/p>\n<ol>\n<li><a href=\"https:\/\/en.wikipedia.org\/wiki\/Nicolosi_globular_projection\">Nicolosi globular<\/a> &#8211; I\u2019ll use this for my overview of the continents. It\u2019s an easy shape to draw and preserves the landmass shapes and directions relatively well.<\/li>\n<li><a href=\"https:\/\/en.wikipedia.org\/wiki\/Cahill%E2%80%93Keyes_projection\">Cahill-Keyes<\/a> &#8211; I\u2019ll use this if I want to preserve the shapes extra well, maybe once I start learning the countries. It keeps landmasses mostly together rather than carving up Antarctica or Greenland. It\u2019s a harder shape to draw, but it\u2019s easier to rough out than the commonly used <a href=\"https:\/\/en.wikipedia.org\/wiki\/Goode_homolosine_projection\">Goode homolosine<\/a>. It preserves directions less well, since the equator meanders up and down, but they\u2019re still stable enough that you can roughly tell where north is. Alternatively I could use multiple <a href=\"https:\/\/en.wikipedia.org\/wiki\/Orthographic_map_projection\">orthographic projections<\/a> centered on each region the way <a href=\"https:\/\/en.wikipedia.org\/wiki\/Wikipedia:WikiProject_Maps\/Conventions\/Orthographic_maps\">Wikipedia displays countries<\/a>.<\/li>\n<li><a href=\"https:\/\/en.wikipedia.org\/wiki\/Robinson_projection\">Robinson<\/a> &#8211; I\u2019ll use this if I want a very easy and familiar way to visualize the whole globe with consistent directions. It\u2019s very well known, since Rand McNally has used it since 1963. The shapes are overall less distorted than many similar projections, but it stretches the shapes near the poles, especially Antarctica, which is smeared all across the bottom.<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"<p>Productivity \ud83d\ude42 I explored the application of CPU scheduling to human task management.
