ContainerDays Boston is a community (un)conference to encourage discussion and learning on the subject of containers and dynamic infrastructure generally. The programme is a mix of OpenSpaces sessions and talks from users, contributors and extenders from all corners of the space. Check http://dynamicinfradays.org/
for more details.
At SCALE 2014 Kir Kolyshkin began by noting that he had previously submitted the same talk title to LinuxFest Northwest but had only managed to come up with six problems at that time. Consequently, he said, the "real" title was now "N problems with Linux containers." But he had come up with a seventh point to discuss this time, he said, so he was pleased to announced that N currently equals 7. Nevertheless, he continued, each problem is really a large topic that could take up a session all on its own.
So at ContainerDays 2015 Kir will give a talk "N Problems of Linux Containers...and Some Solutions".http://dynamicinfradays.org/events/2015-boston/programme.html#nproblems
