CHAOSS project bringing order to open-source metrics

Thursday 12th of September 2019 10:53:11 PM
Providing meaningful metrics for open-source projects has long been a challenge, as simply measuring downloads, commits, or GitHub stars typically doesn't say much about the health or diversity of a project. It's a challenge the Linux Foundation's Community Health Analytics Open Source Software (CHAOSS) project is looking to help solve. At the 2019 Open Source Summit North America (OSSNA), Matt Germonprez, one of the founding members of CHAOSS, outlined what the group is currently doing and why its initial efforts didn't work out as expected.

How to fix common pitfalls with the Python ORM tool SQLAlchemy

Thursday 12th of September 2019 08:24:31 PM
Object-relational mapping (ORM) makes life easier for application developers, in no small part because it lets you interact with a database in a language you may know (such as Python) instead of raw SQL queries. SQLAlchemy is a Python ORM toolkit that provides access to SQL databases using Python. It is a mature ORM tool that adds the benefit of model relationships, a powerful query construction paradigm, easy serialization, and much more.read more

Thursday 12th of September 2019 05:55:51 PM

How Linux came to the mainframe

Thursday 12th of September 2019 11:44:10 AM
Despite my 15 years of experience in the Linux infrastructure space, if you had asked me a year ago what a mainframe was, I'd be hard-pressed to give a satisfying technical answer. I was surprised to learn that the entire time I'd been toiling away on x86 machines in various systems administration roles, Linux was running on the s390x architecture for mainframes. In fact, 2019 marks 20 years of IBM's involvement in Linux on the mainframe, with purely community efforts predating that by a year.read more

When Diverse Network ASICs Meet A Unifying Operating System

And it has also been a decade since switch upstart Arista Networks launched its Extensible Operating System, or EOS, which is derived from Linux. [...] The cross-platform nature of ArcOS, coupled with its ability to run in any function on the network, could turn out to be the key differentiator. A lot of these other NOSes were point solutions that could only be deployed in certain parts of the network, and that just creates animosity with the incumbent vendors that dominate the rest of the networking stack. Given the mission-critical nature of networking in the modern datacenter, it costs a great deal to qualify a new network operating system, and it can take a lot of time. If ArcOS can run across more platforms, qualify faster, and do more jobs in the network, then, says Garg, it has a good chance of shaking up switching and routing. “That totally changes the business conversation and the TCO advantages that we can bring to a customer across the entirety of their network.” Read more

  • Weaveworks Named a Top Kubernetes Contributor

    But anyone who knows the history of Weaveworks might not be too surprised by this. Weaveworks has been a major champion of Kubernetes since the very beginning. It might not be too much of a coincidence that Weaveworks was incorporated only a few weeks after Kubernetes was open sourced, five years ago. In addition to this, the very first elected chair of the CNCF’s Technical Oversight Committee, responsible for technical leadership to the Cloud Native Foundation was also headed up by our CEO, Alexis Richardson(@monadic) (soon to be replaced by the awesome Liz Rice (@lizrice) of Aqua Security).

  • Improving trust in the cloud with OpenStack and AMD SEV

    This post contains an exciting announcement, but first I need to provide some context! Ever heard that joke “the cloud is just someone else’s computer”? Of course it’s a gross over-simplification, but there’s more than a grain of truth in it. And that raises the question: if your applications are running in someone else’s data-centre, how can you trust that they’re not being snooped upon, or worse, invasively tampered with?
