Re: Code Freeze for 0.8

Hi Dr Dunning, Thanks a lot, I just read that the deadline is within 7 days and immediately realize how retarded my plan was. There will be not rc1 or rc2, just rc. Will have to spam some test in the next few days. - Peng On 07/07/2013 10:12 PM, Ted Dunning wrote: Peng, Strictly speaking,

Re: Code Freeze for 0.8

Peng, Strictly speaking, the code is frozen already. Sebastian seems to think some can get in, but even that is pushing things. On Sun, Jul 7, 2013 at 3:59 PM, Peng Cheng wrote: > Hi Dr Dunning, > > I recently joined the team and am working on tickets 1272 and 1274 right > now. I was planning

Re: Confluence Wiki

+1 for CMS + commenting. Confluence is lovely in my experience except at Apache where it has never worked well. On Sun, Jul 7, 2013 at 2:06 PM, Grant Ingersoll wrote: > Anyone know what is up with the Wiki? Seems foobar to me. > > I wonder if we shouldn't export it, clean it and then just p

Re: Code Freeze for 0.8

Hi Cheng, I think we can get 1272 in, the code and tests looks well. I would oppose to include 1274, as it requires a lot of thinking because the API/structure of our recommenders don't support online recommenders very well at the moment. --sebastian On 08.07.2013 00:59, Peng Cheng wrote: > Hi

Re: Code Freeze for 0.8

Hi Dr Dunning, I recently joined the team and am working on tickets 1272 and 1274 right now. I was planning to commit to core-0.8 rc2 but the time frame seems harsh. Could you tell me if is it practical? I'm a hard worker. PS I was there at your presentation in Toronto this year. Not ashamed

Anyone know what is up with the Wiki? Seems foobar to me. I wonder if we shouldn't export it, clean it and then just put anything we want to keep in to the CMS and then use a commenting system like Disqus. -G

Hi all, I did not receive any feedback about this. I understand that now is a busy time with the work on version 0.8. Is there still interest on refactoring the classification APIs once 0.8 is released? Or should I just move on and look for some other way to contribute? I think the changes pr
