Espin references Joe Sharkey's excellent column on in-flight calling in Sunday's New York Times: Sharkey, a veteran travel writer, who survived a mid-air collision over the Brazilian Amazon a few years ago, looks at varying attitudes about calls made during flights. He quotes Aircell's Jack Blumenstein saying what I've telling folks for months: Aircell has a lot of techniques to block VoIP calls already, and "as we identify new ways that people are trying to do voice calls on the airplane, we just kind of zero in and knock those off." Many geeks have assumed Aircell is a bunch of unsavvy folks who wouldn't be able to figure out how to disrupt their clever workarounds for making VoIP. (I keep noting that introducing jitter for suspicious data connections wouldn't disrupt legitimate applications, but would destroy VoIP call quality.)

Given recent media coverage, it’s easy to believe that P2P and streaming video traffic is a rising hurricane battering upon ISP levees, that ISPs are frantically sandbagging their systems against disaster, that throttling, bandwidth caps, and traffic management are urgent and absolute necessities to keep the storm surge at bay. But new research from Telegeography only confirms what we’ve been saying for some time: the Internet backbone isn’t drowning beneath any kind of exaflood. In fact, backbone capacity has grown faster than Internet traffic in the last year—for the second year in a row.

Check out the full article, it even has some shiny graphs. It also reminds me of XKCD the other day… header: “I get in trouble for showing up contented to protests,” and the stick figure’s holding signs: “Things are pretty OK!” and “Anyone for Scrabble later?”

Abstract -- We reverse engineer copyright enforcement in the popular BitTorrent file sharing network and find that a common approach for identifying infringing users is not conclusive. We describe simple techniques for implicating arbitrary network endpoints in illegal content sharing and demonstrate the effectiveness of these techniques experimentally, attracting real DMCA complaints for nonsense devices, e.g., IP printers and a wireless access point. We then step back and evaluate the challenges and possible future directions for pervasive monitoring in P2P file sharing networks.

I’ve heard the buzzwords but wasn’t exactly sure what they meant–luckily, when there’s media hype, there are definitions, too. According to this article, cloud computing is exemplified by Software as a Service — outsourced, hosted platforms and software that perform services for companies.

Another article puts it slightly differently:

OK, let us look at what form of computing in being provided via the cloud. In this model, all IT applications and facilities (i.e. compute, storage and network) are provided as a service rather than dedicated infrastructure. This is intended to allow any user, independent of client platform, to access IT services without knowledge or concern of their location or form. Sound familiar — it’s a service-oriented architecture (SOA)!

In addition, cloud computing incorporates almost every computing manifestation within the IT world: distributed, grid, utility, on-demand, open-source, Web services, P2P, Web 2.0 and, last but not least, software as a service.

It also accommodates thin, thick and mobile clients and allows integration of corporate, commercial and service provider cloud-accessed resources. As an example, in this model, storage is a service resource that is accessed via the cloud, not a dedicated user resource.

Honestly I read that last one first and found the definition a bit dense. It sounds like a summation of everything that makes up our Internet infrastructure already, so how is that different than the Internet itself? Well, cloud computing isn’t about what service or devices are being supported — it’s more about how it’s being provided– it is a location-independent style of computing. The first article calls it “platform as a service.”

Have you heard better definitions of what cloud computing is and does? Share them in the comments below. Thanks!
