Announcing the Open Source License API

Over the last 19 years, the Open Source Initiative (OSI) has been the steward of the Open Source Definition (or OSD), establishing a common language when discussing what it means to be an Open Source license, and a list of licenses which are known to be compatible with the OSD.

This is taken to its logic next step this year, with the OSI providing a machine readable publication of OSI approved licenses at api.opensource.org. This will allow third parties to become license-aware, and give organizations the ability to clearly determine if a license is, in fact, an Open Source license, from the authoritative source regarding Open Source licenses, the OSI.

It’s Sunday, and it has been two weeks since the release of the Linux 4.6 kernel, so the time has come for Linus Torvalds to introduce us to the development cycle of the next major kernel branch.

Yes, we’re talking about Linux kernel 4.7, which has just received its first Release Candidate (RC) build. It allows the community to download it, compile it for their GNU/Linux systems, and take it for a long weekend test drive, especially now that the merge window has finally been closed by Mr. Torvalds, probably a little bit earlier than expected.

3 Things Infrastructure as Code Is Not

The role of the network engineer is changing. This is not a result of DevOps, although some would claim it is. As DevOps takes center stage in organizations, it can seem like network engineers are being asked to become developers.

There have been a number of talks discussing this, some of which have surfaced at Interop Las Vegas. The shift has been Infrastructure as Code (IaC), which was fundamental to the start of the DevOps movement. So maybe you could say this is caused by DevOps.

IaC is providing an approach to employ code to the Ops infrastructure. Companies like Ansible, Chef, Puppet, and Cumulus Networks have made this shift possible. The tools provided by these companies have made the DevOps culture possible, and IaC is a large result of this.

Set up Gnome Desktop && VirtTools on Virtualization Server ( VIRTHOST ) and make remote connection to Virt-manager running on VIRTHOST (192.168.1.75). Then create VM via virt-manager as follows using standard CentOS 7.2 ISO image , I am aware of post Connecting another vm to your tripleo-quickstart deployment at oddbits.com and manage this way deliberately. Just wondering is it possible to get results similar to obtained by LarsKS ( via in depth knowledge virsh CLI and Libvirt features) with Virt-manager GUI intuitively much more affordable. I realize that speed and flexibility of approach suggested bellow are losing the aforementioned

SD-WAN Demands Different Network Monitoring

ThousandEyes, a company that does network monitoring, says software-defined wide-area networking (SD-WAN) is making visibility more difficult, so it has created agent-to-agent tests to make it easier to pinpoint issues in both the forward and reverse paths.

SD-WAN is becoming a popular technology for organizations looking to manage multiple Internet connections, but “it’s introducing new variability in routing,” says Nick Kephart, senior director of product marketing at ThousandEyes. “Now, if you need to troubleshoot, you need a more detailed perspective.”

Prior to SD-WAN, a typical WAN connection might be a single leaf from one provider. But with SD-WAN, traffic can move through different networks in each direction.
