Shellshock: One Month On

Shellshock was released a little over a month ago, to wide predictions of doom & gloom. But somehow the Internet survived, and we lurch on towards the next crisis.

Disappointed With Check Point

I have recently started working with Check Point products again, after a 5-year break. This has given me a different perspective on how they are progressing. It has been disappointing to see that they’re still suffering from some of the same old bugs. Some of the core functionality is now showing its age, and is no longer appropriate […]

The Chassis Switch is Dead

The Chassis Switch is Dead. For most networks, chassis-based switches are no longer appropriate due to cost, inflexibility and risk. I see this as similar to servers, in that server blade chassis are no longer appropriate for most organisations. The alternatives are already better for cost & flexibility.

Let People Choose Their Own Tools

Why is it that people will pay a lot of money for a consultant’s time and expertise, but then hobble them by limiting the tools they can use? Chris Wahl has written about learning to cope with the default tools and settings: It’s almost a given that anything I own – personally or via my employer – […]
