Introducing Futuri Media

February 04, 2015 at 12:00 PM    

The middle of last year I started working with a media technology company in Cleveland (LDR Interactive) as their CIO. We have been innovating very quickly on infrastructure and new products.

Today the company is being relaunched as Futuri Media. This is the fruit a 7 month strategic overhaul to reflect the success of the company since its inception in 2009 - working with over 400 stations in 11 countries; being named to the Inc 500 Fastest Growing Private Companies; and reaching over 100M consumers each month.

It is an amazing team and leading them through this growth has been a great experience. The next chapter is going to be even better!

IBM Research Report: An Updated Performance Comparison of Virtual Machines and Linux Containers

August 07, 2014 at 01:58 PM    

[PDF] Interesting research report from IBM comparing performance of docker vs KVM. I would have liked to see Xen instead of KVM. Obviously full virtualization has more overhead than containers, but there are decent trade offs to this in terms of flexibility and security. Docker is getting to be quite flexible though, and has some benefits. I don't know that performance will be the key criteria for picking a side (Containers vs. Virtualization)

Containers vs Hypervisors

April 16, 2014 at 07:32 PM    

Dr Who references aside, there is an interesting debate forming over implementing virtualization with containers instead of hypervisors. Many application servers use the container model and while there are some benefits I don't know that I agree about the concept of delivering more services. There is much duplication in the container model and hypervisors try to reduce that since it is essentially wasteful. Some of the problems with hypervisors, such as hoggy neighbors and "cpu stealing" are not addressed with the container approach.

If you have browsed my HTML code you see that I have been flapping back and forth on closing void tags in HTML. I am not alone in this conceptual tug-of-war. My thought has been that it is more technically correct to do so, even though it is optional and makes for ugly code prose. This article goes through the history of the concept and where current thinking/standards lie. TL;DR version: Closing them is out of style in HTML5. Your code can be pretty _and_ correct.
