Hi all, I've written a brain dump of what went on behind the scenes at IOI 2013, with possibly way too much detail. It touches on some things about CMS, and general stuff about organising the IOI competition hall. https://docs.google.com/document/d/1cwvWVOWRhsnDib9UqcmfZlfrHQ1Vq6rpx7YzRo48OV8/pub As mentioned there, I'll be cleaning up and submitting the patches we have for CMS back upstream. A big thank you to everybody who has contributed to CMS. We were running close-to-bleeding edge CMS and apart from a couple of issues described there, it was pretty solid! Cheers, Bernard.
