There is and always shall be order in the universe. All things have order of some form. When we observe the murmuration of birds (flying in a swarm like pattern), we at first see chaos, but then as we observe more closely we note form. Rarely ever do these birds collide in air. It is amazing to watch literally hundreds if not thousands of birds flying in a clump and moving in unison. read more

The next version of ownCloud, the personal cloud server, adds enterprise-level scalability and collaboration improvements.

You'd be hard pressed to find someone who wouldn't agree that design for open source projects in a broad sense (websites, materials, logos, and so on) couldn't use a bit of... finesse. Or perhaps, just a touch more forethought and a good designer on hand. Bermon Painter and his collegues in the field of design and user experience know this all too well and are trying to change the way designers contribute to and participate in open source projects.

Sometimes it's necessary to change function semantics inside the kernel, and then find and update all users of that function to match the new semantics. Such changes can result in huge patches going into the source tree, affecting hundreds of files.

One of the benefits of the ownCloud architecture is that it scales from small installations, such as a Raspberry Pi for 1-10 users, to up to 500,000 users and a petabyte of storage running in a powerful cluster setup. Together with research organizations CERN and AARnet, we've been collaborating to bring this to a new level—breaking through the petabyte barrier together. read more

When I think about what makes SageMath different from other math software systems, it's one of the most fundamental things about it: SageMath was created by the very people who use it every day. These researchers, teachers, computer programmers, and engineers are the ones who fully understand computational problems because they live them. read more
