Not sure I agree with "hastily launched". First public commit to the github repo was January 14th 2014.

The presumption that this or Google's Tensor Flow can be cobbled together in a few hours is completely absurd. These things take months if not years of development. And releasing them into the wild is not a process that takes 30 minutes. Open Sourcing a company library is a work intensive process that takes weeks if not months. Beyond the code itself there are a swatch of promotional materials to prepare.
That said, I do agree that the submission itself to HN was in response to Google's Tensor Flow announcement. The submitter created their acct an hour ago and the only other activity is a comment on the google announcement talking about veles.
Also the submission title was unnecessarily snarky.
