Blogging In Transition: A Host Of Issues – Act One

In the three years since it began this blog has been through a number of transitions. The most recent being just a few weeks ago. This is a little tale of that experience, offered to help anyone else who might be following a similar path. This little drama comes in the form of three acts. In this first act we examine the history of the site that lead up to recent events.

My efforts at blogging began in fall of 2007 on the free hosting at WordPress.com. While a fine place to get started I eventually wanted to tweak WordPress beyond the scope that was allowed on that service. In particular, the desire to include more multimedia content provided the motivation to move the site to a paid host.

VUC Video Calls: A Two Act Play

As many of you may know I’ve been trying to put together a video call for the VUC over the past few months. After a lot of thought, but little action, act one of this little project will get underway this coming Friday, August 13th at 1pm EDT.

The basic idea for the project has been with me for a year, ever since I trialed the Polycom VVX-1500 video phones last summer. It evolved as I was later asked to research video conferencing systems for my employer, a project which was eventually tabled in Q4/09.

There are quite a number of factors to consider when you’re thinking about implementing a video conference solution. At its most basic I needed in some substantive way to grasp the difference between one-to-one video calling using desk phone, traditional video conferencing and “Telepresence.”

Evolving The Mobile Data Billing Model

AT&T 3G USB DongleEarlier this week AT&T has its quarterly earnings call. Normally I would not give it any notice at all. It’d just be another bunch of noise in my Google Reader in-box. This week they did something that simply jumped out at me; they called for an evolution of the current billing model for mobile data plans. Oddly enough…I agree…sort of.

Of course, their perspective on this is not quite the same as my own. AT&T want to be rid of the $60/mo for all-you-can-eat billing model and charge based upon actual usage, perhaps in some sort of tiered fashion.

Literally everyone knows that the current billing model is badly broken. Their flat rate “unlimited” plans are not really unlimited at all. My Sprint 3G service was pretty plain about it being capped at 5 GB/month. Beyond that I’d guess that it gets costly. Moreover they claim performance levels that almost no-one ever achieves in practice.

Amazon Responds About SIP Attacks From EC2

On April 18th Amazon finally responded publicly with respect to the SIP attacks recently suffered from hosts within their EC2 service. Their response comes in the form of an informational security bulletin posted to their AWS Security Center.

There have been some recent discussions about SIP brute force attacks originating from Amazon EC2. We can confirm that several users reported SIP brute force attacks originating from a small number of Amazon EC2 instances about a week ago. It appears these attacks were designed to exploit security vulnerabilities in the SIP protocol. There is nothing specific about this attack that requires Amazon EC2. It was a brute force attack that could be launched from any computer on any network.

Video Conferencing & Volcanic Ash

The volcanic eruption in Iceland, and its associated ash cloud, has certainly been a major topic of discussion this past week. My brother and his wife were caught in France on vacation. Their two week skiing vacation has become three weeks, quite unexpectedly.

Further, while we were focused on the NAB convention in Las Vegas three of my UK-based associates ended up extending their stay in the US by over a week, unable to get flights home. I suspect that I’m not the only one wishing that we had pushed forward with our plans to install room type video conference systems in Cambridge and Burbank. Those systems would certainly have been very handy this week.
