What it does
Pa11y aims to improve the accessibility of the web through better tooling and automation.
Pa11y is your automated accessibility testing pal.
Here at Pa11y, we think making the web more accessible improves it for everyone. So we publish a range of free and open source tools to help designers and developers make their web pages more accessible: A command-line interface which loads web pages and highlights any accessibility issues it finds. Useful for when you want to run a one-off test against a web page. A web dashboard which automatically tests web pages for accessibility issues daily. Graphs help you track improvements and regressions over time. Useful for non-developers to see how your sites perform. The JSON-based webservice that backs Pa11y Dashboard. Useful if you want to build your own dashboard-like front end, or…from pa11y.org

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

After years of solo development I'm presenting: Angeldust, an omni-compatible action RPG and building game! Website: http://angeldu.st My single server hosts 250+K active players in one giant, dynamic fantasy world. Angeldust's game server is pervasively multithreaded, implementing John Carmack's dream of processing an immutable world state each tick. Both world handling and network traffic routing uses any number of threads. For networking, a typical game session only uses ~3Kbps of bandwidth, enabling decent play even over 2G/EDGE networks. The client is programmed in C++…
