Speeding up the Debian installer using eatmydata and dpkg-divert
The Debian installer could be a lot quicker. When we install more than 2000 packages in Skolelinux / Debian Edu using tasksel in the installer, unpacking the binary packages take forever. A part of the slow I/O issue was discussed in bug #613428 about too much file system sync-ing done by dpkg, which is the package responsible for unpacking the binary packages. Other parts (like code executed by postinst scripts) might also sync to disk during installation. All this sync-ing to disk do not really make sense to me. If the machine crash half-way through, I start over, I do not try to salvage the half installed system. So the failure sync-ing is supposed to protect against, hardware or system crash, is not really relevant while the installer is running.
Samsung's first open-source conference kicks off, with Tizen on its mind

Flockport Rivals Docker with Open Source Container Virtualization
Is there more to container-based open source virtualization than Docker? A startup named Flockport thinks so, and has launched a website for sharing and deploying virtual apps using Linux Containers (LXC), an alternative to Docker.
OpenDaylight executive director spells out where this open source SDN efforts stand
So if I compare it to Linux. Linux is in my computer, in my car, it’s in a million things outside of the server room. In the same way I think a large percentage of OpenDaylight will be used and leveraged that way. You will have a few people who grab the code, compile it themselves and deploy it in their environment, but mostly for a proof of concept (POC). If an end user hears about SDN and thinks it’s great, they might find themselves needing to POC 15 different solutions. Do I need an overlay? Well, you’ve got to look at three or four overlays out there because they all do things differently. And if you want to figure out how to use OpenFlow, well there are different flavors of OpenFlow, so you’re going to pull a couple of different ones.
