Those are the words of W. Edwards Deming, the champion of statistical process control, who was credited as one of the inspirations for what became known as the Japanese post-war economic miracle of 1950 to 1960.

Faucet: An Open Source SDN Controller for High-Speed Production Networks

Wed, 01/16/2019 - 06:24

Open standards such as OpenFlow and P4 promised to improve the landscape by opening access to these devices via a programmable API, but they still require someone to write a controller to re-implement normal switch functionality, such as forwarding and routing, in a multi-vendor, standards-compliant way. This led our group to write the Faucet software-defined network (SDN) controller, which allows anyone to fully realize the dream of programmable networks.

Ansible vs. Puppet: Declarative DevOps Tools Square Off

Wed, 01/16/2019 - 05:12

DevOps aims to drive collaboration between development and operations teams, but software quality drives DevOps adoption more than any other factor. As this comparison of Ansible vs. Puppet shows, software quality dramatically influences DevOps tools.

Software quality tends to be an organizational goal or a staff function, not the dominion of a dedicated group with broad responsibility to implement its decisions. Effective software quality efforts involve everyone from development to production users to ensure real value.

Tue, 01/15/2019 - 05:28

Undoubtedly, your company uses open source software. But the powers that be might express reluctance when developers want to create or maintain projects on company time. Here is a roadmap to help you convince them otherwise—starting with an internal open source project office.

Open source innovation has a methodology all its own, and it doesn’t follow traditional business processes. The big difference is that open source development is collaborative rather than competitive. This attitude may come naturally to IT people, but not to managers and rarely to people in the C-suite....

(Don't) Return to Sender: How to Protect Yourself From Email Tracking

Mon, 01/14/2019 - 05:35

Responsible tracking should aggregate a minimal amount of anonymous data, similar to page hits: enough to let the sender get a sense of how well their campaign is doing without invading users’ privacy. Email tracking should always be disclosed up-front, and users should have a clear and easy way to opt out if they choose to.
