Hi Sterling, This looks really interesting.
If you’re interested in adding another mentor, I’d be happy to volunteer. -Taylor > On Oct 8, 2015, at 12:20 PM, Sterling Hughes <sterl...@apache.org> wrote: > > Hi All, > > All feedback thus far has been positive, so unless anyone objects, I > plan to move to a VOTE either tomorrow or Monday. > > Thanks, > > Sterling > > > On Mon, Oct 5, 2015 at 9:39 AM, Sterling Hughes <sterl...@apache.org> wrote: >> Hi! >> >> We would like to start a discussion on accepting Mynewt, a RTOS (real-time >> operating system) for Internet of Things devices, into the Apache Incubator. >> Please take a look at the proposal and let us know any comments or feedback >> you have.
