Debian donation for Peertube development

The Debian project is happy to announce a donation of 10,000 USD to help Framasoft reach the fourth stretch-goal of its Peertube v3 crowdfunding campaign -- Live Streaming. This year's iteration of the Debian annual conference, DebConf20, had to be held online, and while being a resounding success, it made clear to the project our need to have a permanent live streaming infrastructure for small events held by local Debian groups. As such, Peertube, a FLOSS video hosting platform, seems to be the perfect solution for us. We hope this unconventional gesture from the Debian project will help us make this year somewhat less terrible and give us, and thus humanity, better Free Software tooling to approach the future.

  • Wikimedia’s CDN

    The Wikimedia Foundation, the non-profit organization behind Wikipedia and other well known wiki-based projects, operates websites and services that are high volume and rank in the world’s top 20. We serve about 21 Billion read requests per month and sustain 55 Million edits to our articles. On a normal day over 90% of these read requests are served by our caching solution, our own Content Delivery Network (CDN). Like other parts of our technology stack, the CDN is based on Open Source software and is constantly evolving. During the last couple of years, we have performed various changes in terms of on-disk HTTP caching and request routing.

    This 3 part series of articles will describe some of the changes, which included replacing Varnish with Apache Traffic Server (ATS) as the on-disk HTTP cache component of the CDN. ATS allowed us to significantly simplify the CDN architecture, increase our uptime, and accelerate the procedure to switch between our two primary data centers in Virginia and Texas.
