Refactoring Consumer Electronics 12/24/2012 (Updated: 10/19/2014)
Article in the January 2013 issue of the IEEE Consumer Electronics magazine. The concepts behind the Internet -- the best efforts exchange of raw bits -- represents a basic shift from a framing of electrons and pipes to one in which we can focus on relationships and applications. (The IEEE version is available here
Connected Things 10/16/2014
The power of the Internet comes from our ability to build connected applications. We use the term “Internet of Things” to extend this concept beyond computation to include the objects in the physical world.
Connectivity Policy 7/17/2014 (Updated: 7/31/2014)
The internet is a different way of using the same facilities (wires, radios etc.) used for telecommunications. The big difference is that the Internet approach is not limited to provider-defined for-profit offerings. The differences go far deeper.
I use the term "borderless connectivity" for the new concept. The approach is being adopted from the edge -- driven by market forces. Telecommunications becomes just another resource as one way to extend connectivity as we shift from being dependent upon service providers to creating our own solutions.
Today's Internet gives a hint of what we can do with the new opportunities.
(Not) Getting the Message Across 6/30/2014
If we are to get the benefits of the Internet's connectivity we need transparent paths without intermediaries either to press "agree" or having protocols like Bluetooth which insist on "understanding" the messages before passing them on.
HTML5 is becoming the very portable virtual machine that makes it easy to create and share rich interactive applications.
Comsos - Science and motivation 3/8/2014
We should applaud efforts to broaden interest in science. The reason science funding is often driven by the military is not because we like war but because we fail to appreciate the value inquiry.IPList
Thinking Outside the Internet 3/7/2014
In order to understand the importance of connectivity we have to think outside the paradigm of pipes or channels that characterized classic period of networking dating back to Shannon. The Internet itself is about borderless connectivity with the value and meaning outside the channels.This has strong implications for how we provide (and fund) the opportunity we associate with "The Internet"CircleID
MAC addresses and Tracking 2/13/2014
We need to remember that many of the constraints we try to work around are simply engineering and policy decisions. We could revisit them rather than trying to work around the problems. The MAC addresses and the channels we use to communicate are just constructs.IPList
Routing (Packets) vs. Gatewaying (Messages 1/23/2014
Our smart phones are wonderful devices with many functions built-in. This is in contrast with the simplicity of the Internet in which we simply route packets of bits rather than having to wait for third parties for each message. I contrast the simple routing of packets with the complexities of gatewaying messages with service providers attempting to “add value” to our relationships.
Evolution and the Internet 1/6/2014
Understanding how systems evolve is as much about the Internet as biology. We need to understand that the Internet wasn't designed as much as evolved as we discovered how to communicate without depending on a third party in the middle of the conversation.CircleID
Life (yet to be) Scripted 12/23/2013
The goal of "home automation" seems to write rules to control our homes (and our lives) as if we were setting rules for a very smart butler. But the real world is more complicated and computers aren't omniscient butlers who can read our minds and anticipate every eventuality.
