I was happy to read about the new features in the latest release of the Wikimedia Commons app for Android. My understanding is the app is developed and maintained by community members with funding from WMF and GSoC in addition to volunteer time.
Also, I was happy to see GSoC participants introducing themselves and their projects on Wikitech-l.
I am grateful to the WMF staff who are listening and responding civilly to the questions and comments on MediaWiki regarding the page previews feature. The project plan appears to have been designed thoughtfully.
Finally, I liked reading portions of English Wikipedia's article about CubeSats.
What's making you happy this week? You are welcome to comment in any language.
