Automate All The Things? Maybe Not

I’m fundamentally lazy. That’s why automation appeals: less work for me. Get the machine to do it instead. But automating everything isn’t always the right answer. Sometimes you need to ask yourself: Does this task need to be done at all? Or can I get someone else to do it for me?

What's In My Bag (Hint: not much)

Recently @BobMcCouch posted a photo of the contents of his bags. He’s got a lot of gear, including a hammer, and a dent-puller. He assures us that it’s for lifting tiles, but I’m not so sure. Sounds to me like he’s worried about a few dings in the supermarket carpark.

The Year of IPv6?

IPv6 adoption has been slow. But I think it’s reaching a tipping point. I’m very close to calling 2015 “The year of IPv6.” There’s plenty of people who won’t believe me, but the statistics are very interesting. You need to keep a close on eye on what the data is saying.

Indeni, Smart Advisors and Crowd-Sourcing

Monitoring needs to move on from traditional fault and performance polling. It should include identifying common misconfigurations and known faults. We’re all using the same technologies, so we’ve all got the same problems. I like the look of Indeni, a new approach to this problem. It uses a form of crowd-sourcing to act as a smart advisor.
