CouchDB Certification? (see thread)
Planning to organise a NoSQL/CouchDB course for computing learners, a user has asked for an official or certified graduation test for CouchDB. While there isn’t any official certification that CouchDB learners can obtain, the CouchDB community is very open to support efforts learning, teaching and mentoring of any kind. It is also very welcome to share experiences, insights and materials that the community and other learners or teachers can benefit from. You can also write about them, e.g. on the CouchDB blog. Please don’t hesitate to submit your ideas to the list at firstname.lastname@example.org.
Performance tuning and optimization guidelines (see thread)
On the user@-mailing list, it was asked for certain documents describing performance tuning parameters for CouchDB. The answer refers to the docs that describe all configuration parameters in CouchDB.
Query view with keys, is order guaranteed? (see thread)
A user wants to know if a particular order behaviour with multiple-key querying will be reliably preserved in future versions of CouchDB, which isn’t a committed behaviour and therefore isn’t guaranteed at the moment.

- “In 2013, I began celebrating career achievements by eating a donut. I had found that whenever something awesome happened in my career—maybe I got published, or promoted, or launched a project—I wouldn’t take the time to celebrate the achievement… I decided to start celebrating in a public way so that more people may be inspired to find their own ways of marking their career achievements.” – Celebrating our achievements

- “Even if it’s by accident, nerd culture does tend to exclude women and LGBTQIA+ people in a bunch of different ways. This sucks – because nerd culture is supposed to be the culture of the neglected. It’s the culture of the people who were never popular in high school or never had a lot of friends or were bullied for one reason or another. As a culture basically founded on being outcasts, I think it’s absolutely necessary that we be as open and accepting as possible.” – Nerd Culture Has a Problem – Here Are 5 Ways to Be More Inclusive
