I just discovered that Gantt has been proposed as a potential subject of interest for GSoC. While I do understand the opportunity for people working on Gantt, I don't think, as Russell stated, that Gantt is mature enough for helping newcomers to deliver cool
features within the given timeline.<br>
<br>
IMHO, Gantt should be removed from this wikipage [1], and be replaced by Nova proposal for Filters/Weights improvements. The Solver Scheduler recently received NACK for a FFE (Feature Freeze Exception) so that means that new patches wouldn't be merged until
Juno (12th May), so I guess the problem would be the same too.<br>
<br>
Anyway, people interested in working on the Scheduler should attend weekly meetings on Tuesdays, for at least synchronization within the team.<br>
<br>
My 2cts,<br>
