The Dirty Secret of Team Collaboration: Teams

Cisco Spark teams is really simple. A team is a group of people working together. Anyone can create a team and then add users to it. A team can have any number of rooms, which are topic-specific rooms used by that team. Anyone in a team can create these “team rooms.” As a team member, I can easily see all the team rooms I’m not in, check them out, and join or leave them at will. That makes Cisco Spark a great experience for new users joining the app for the first time, or joining a new team.

A Lesson from Goldilocks: Messaging Security that’s “Just Right”

We all know the story of Goldilocks and her ill-fated visit to the house of the three bears. What lesson, if any, one might take away from this story is that too much of a good thing doesn’t necessarily make it the right thing. Big chairs are big, but if they’re too big, they’re not comfortable. What is true for Goldilocks – and bear with me on the analogy – is also true when considering security technologies for business. When evaluating messaging technologies, the question to think about is: What parties should have access to content, and which should not?

Often ignored, considered as an afterthought, and staffed by “someone else” who did an important job but was outside of the core development process. Well, that has all changed. In the SaaS world – especially one […]

Devops Means “No, you cannot operate my cloud”

One of the things I really believe strongly is that modern SaaS software development – both the practices and code it produces – are significantly different from traditional enterprise premises-based software development. Yet, I find that for people who have never built and operated a modern SaaS platform, these differences are difficult to grasp.

The Four Dimensions of Open

Last week, I posted about our Project Thor, our effort at creating a royalty-free next-generation video codec. This post generated lots of comments – which is great! But also illustrated that there is a lot of confusion about what it means for something to be open. I’d like to remedy that here and describe the […]
