Wikimedia Foundation donations received

This is an online portal with information on donations that were announced publicly (or have been shared with permission) that were of interest to Vipul Naik. The git repository with the code for this portal, as well as all the underlying data, is available on GitHub. All payment amounts are in current United States dollars (USD). The repository of donations is being seeded with an initial collation by Issa Rice as well as continued contributions from him (see his commits and the contract work page listing all financially compensated contributions to the site) but all responsibility for errors and inaccuracies belongs to Vipul Naik. Current data is preliminary and has not been completely vetted and normalized; if sharing a link to this site or any page on this site, please include the caveat that the data is preliminary (if you want to share without including caveats, please check with Vipul Naik). We expect to have completed the first round of development by the end of March 2022. See the about page for more details. Also of interest: pageview data on, tutorial in README, request for feedback to EA Forum.

Knight Foundation600,000.005--Technology Grant period: 03/21/2013 - 04/20/2015; part of the challenge: Knight News Challenge; goal: For creating tools to deliver Wikipedia for free to users in the developing world As mobile technology is increasingly the primary opportunity for billions of people around the world to access the Internet, the Wikimedia Foundation is working to remove the two biggest hurdles to access free knowledge: cost and accessibility. News Challenge funding will help create software to bring Wikipedia to lower-end, more basic phones - the kinds the majority of people use to access data outside of the West. Specifically, efforts will be focused in three areas: developing features to improve the mobile experience regardless of how feature-rich the device is – including new ways to access Wikipedia via text; increasing the number of languages that can access Wikipedia on mobile; and improving the way feature phones access the platform.
