There is a technicality concern based solely on vague and very non-specific communication of intended contributor. However, since prototype is not made available to Mahout community, there's no way to either confirm, refute or resolve this -- or any other -- concern at this point. No physical & tangible contribution -- no concerns. Can't be. There are of course plenty of cases when closed project becomes open, but usually this either goes through Apache incubation process, or there's a legitimate reason to keep it closed (e.g. novel methodology and patent or publication pending). If none of this apply, i would respectfully urge the perspective contributors to submit their work for early review, assuming everyone is holding Mahout community interests dear first. The reasons to make prototype and TDD available early include: -- eliminate all sorts of speculative thinking per above. The sooner we do that, the less speculations we'll produce in waiting. -- it is hard for committers to do a quality review on a super-massive commit dumps due to time constraints. It is much easier to do so in steps and portions. -- failure to engage community into the effort: No coder alone making any changes to Mahout code could reliably assert that they are not creating problems for Mahout and/or outside users, since no one has the entire Mahout picture in his or her head. We need the entire community to assert benign nature of Mahout code modifications or additions. -- it is also more expensive to resolve architectural problems once siginficant amount of changes is made, it would be a bit of "my way of highway" way of offering things. -- development of intended open software contribution that is available only to corporate entities, is not, well, open by definition. > > > On Fri, Apr 4, 2014 at 6:47 PM, SriSatish Ambati <[email protected] > >wrote: > > > Grant, > > On 0xdata / H2O front: > > > > We feel very excited at making Apache Mahout the principal platform for > > scalable machine learning and are rapidly prototyping an initial > > integration with the Matrix API.
