1. Finding Value in Cisco Live 2018 – Networking Nerd
Tom Hollingsworth (a.k.a the Networking Nerd) wonders if Cisco Live is still worth all the money, and if there are too many events, lounges, gatherings, tweet-ups, meet-ups and so on that distract from core activities such as courses and sessions.
2. Why, as a Netflix infrastructure manager, am I on call? – Medium
One of the perks of moving up the ranks is not having to be on call. But Andrew Spyker, a manager at Netflix, keeps himself in regular rotation with full pager duties. When an engineer asked if it was because he didn’t trust his team, Spyker decided to lay out his reasons, both good and bad.

4. Another 10 Years Later – The ISP Column (Geoff Huston)
Geoff Huston reflects on the last ten years of development (and some stagnation) in Internet technology. As he writes “Ten years ago, I wrote an article that looked back on the developments within the Internet over the period from 1998 to 2008. Well another ten years has gone by, and it’s a good opportunity to take a little time once more to muse over what’s new, what’s old and what’s been forgotten in another decade of the Internet’s evolution.”

3. Verizon and AT&T will stop selling your phone’s location to data brokers – Ars Technica
It almost seems like ISPs want to be hated by their customers. If there’s a despicable business practice they can adopt, they’ll adopt it and run as fast and as far as they can until they get busted. Jon Brodkin writes “Verizon and AT&T have promised to stop selling their mobile customers’ location information to third-party data brokers following a security problem that leaked the real-time location of US cell phone users.”
4. Network Engineers Feel Pressure to Embrace DevOps Practices – SDX Central
“…it’s now only a matter of time before networking administrators are going to be asked to make resources programmatically available. The issue they will need to come to terms with is to what degree they will want to expose application programming interfaces (APIs) to achieve that goal versus providing access to a self-service portal through which developers are able to access a fixed amount of resources.”
