Atlas of Economic Complexity – interactive map of global economies
🔗 Atlas of Economic Complexity is an interactive data platform developed by the Center for International Development (CID) at Harvard University. It offers a sophisticated lens for examining how economies grow – not just through output or GDP, but by analyzing the complexity and diversity of what countries produce and export.
At its core, the Atlas is based on the Economic Complexity Index (ECI) – a metric that doesn’t simply measure how much a country exports, but how advanced and diversified those exports are. Nations exporting only raw materials typically score low, while those exporting specialized machinery, chemical compounds, or electronics achieve high complexity scores. The higher the ECI, the greater the latent capacity for sustained economic growth.

ExplainShell – Understand Shell Commands, Line by Line
🔗 explainshell.com is a brilliant utility for anyone working with Linux or Unix shell environments. While basic commands like cd or ls are commonly understood, more advanced command-line expressions can quickly become cryptic. That’s where ExplainShell shines – helping you understand exactly what each part of a command does.
The interface is refreshingly simple: paste in any shell command (e.g., tar -xzvf archive.tar.gz or find . -type f -exec grep -H 'pattern' {} \;) and the tool immediately dissects it. It maps each argument, flag, and operator to documentation snippets pulled from real man pages. You don’t just get a general explanation — you see which part of the command corresponds to which official description.

🔗 randoma11y.com is a surprisingly effective minimalist tool designed for web developers, interface designers, and accessibility advocates. Its main purpose is to generate random background/text color pairs that meet the WCAG 2.1 contrast ratio requirements, making them readable for people with visual impairments or low vision.
Upon each refresh, the site presents a new color combination, displaying both HEX values, the exact contrast ratio (e.g. 9.41:1), and a ready-made CSS snippet. Visitors can vote on whether the combination is good or bad, slowly building a kind of crowdsourced archive of aesthetically pleasing and functionally accessible color sets.
