Leading cross-functional teams: foot-in-the-door theory
When I was at Juniper, my job was basically to sell internally those ideas that were deemed so controversial or hotly contested that no one could get them through the corporate machinery. This put me in a position that I was almost always leading cross-functional teams whose members did not directly report to me. I […]

Five selfish reasons to interview candidates
Lets be honest. It is hard to justify the time needed to interview people. It can be really hard to motivate yourself to interview potential new hires when project deadlines are looming. It is perfectly fair to ask yourself, “what’s in it for me?” I think there is a payoff for time spent on hiring. […]

Finding a New Path (Part 1)
In my last installment on the topic of fast convergence, I said I’d be discussing the calculation stage of fast convergence next. Orhan tried to scoop me in the comments, but that’s okay –I’m working at this through the process switched path, rather than interrupt context. In parallel with flooding information about the topology change […]

Professional Loneliness
Lately I’ve been bouncing some generic DMVPN questions off the twittersphere. I’ve used DMVPN sporadically in tiny single-use cases before, but now I am planning to roll out a somewhat larger implementation with a dual cloud and dual hub, complicated by the fact that I don’t control the perimeter router at our DC and I […]

The Priorities Bill of Rights – 10 practical steps to managing group priorities
Managers everywhere are abusing their employees by using priorities to convey to-do lists. It is not because of anything insidious in their objectives, but the average manager (both low- and high-level, by the way) simply doesn’t think enough about priorities to really do anything meaningful with them. For teams I lead, our entire existence revolves […]

Forum Going Away – But New Things Are Coming
Roughly a year ago, we built forum.packetpushers.net. This was a forum site built on vBulletin. The idea was to give the community another place to exchange ideas, share information, and help each other with challenges.

IT’s Not Just About Technology
There’s a lot of great blogs and resources that get really deep into specific areas of tech. While it may sound really strange, this site is decidedly not one of them. The focus of The Tech Interview is quite different. Instead of focusing on the bits and bytes of technology, we look at the un-tech […]

Automation : Not Just Marketing Fluff

More Snowden Media Douchebaggery
I previously wrote a post in response to an article that equated Snowden’s CEH certification to James Bond’s “license to kill.” Well, it looks like some technically-challenged media types are at it again. They’ve called Snowden “brilliant” for his ability to “impersonate” users on various systems in order to obtain certain documents and I felt […]
