CBC Radio’s Spark On Soundscapes: Cutting Through The Noise

I’ve recently discovered a CBC Radio program called Spark. The CBC is a bone fide national treasure, and Spark is their program on technology in society. They describe it as:

Spark is a weekly audio blog of smart and unexpected trendwatching. It’s not just technology for gearheads, it’s about the way technology affects our lives, and the world around us.

…sounds interesting, non?

I recently loaded my phone with some Spark podcasts in a effort to catch up on the program. I was especially taken by episode 128 from November 2010 which considers the impact of noise on people. From the calming influence of bird song to the stress induced by using a cell phone, it’s profoundly interesting stuff.

Our personal and collective productivity often hinges on the soundscape of the working environment. Your personal stress and anxiety level can also be impacted. To be blunt, noise matters…and yet it’s often completely overlooked.

You may have noticed the widget that I added to the sidebar about a week ago. Inspired by hearing about Voxeo’s Phono on a recent VUC call I decided that I’d like to provide a mechanism for readers to leave comments in the form of a voice message.

This seemed like it would be really easy, even though I’m not a developer. I was particularly happy to see that there is a WordPress plugin called WordPhone that makes this practical for the complete newby.

Power To The People: Without Interuption!

Earlier this evening Leo Laporte of TWiT fame tweeted the following:

Power is out in Petaluma. TWiT Live is down until it returns but no ETA. Thank goodness for the iPad 3G. http://j.mp/dt8Oii

I must admit that I am surprised and a little shocked that such an incident would take TWiT Cottage off-line. Leo Laporte is unusual amongst the online media community. His TWiT related endeavors are an unparalleled success. His transformation from traditional to online media is the stuff of future textbooks.

An enterprise such as TWiT should not be taken down by something so simple as a power outage when standby generators are sold at every Lowe’s and Home Depot across the country.

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.

CSPAN Interview On The New National Broadband Plan

The FCC's Blair Levin, Executive Director of the National Broadband Initiative, discusses reactions from legislators, the telecommunications industry and public interest groups to the plan. This will ultimately effect us all, so it's good to stay informed as the matter…

A Tale Of Wonky Wifi Part 3: Wifi Access Point vs Router

There are myriad inexpensive consumer routers available that include wifi functionality, but far fewer freestanding wifi access points (AP.) I surmise that this is because every broadband connected home needs a router and wants a wifi AP, so a converged device is the most affordable approach to this marketplace. Yet in many ways it’s less than ideal.

The fact that your router and wifi access point are in one device makes that device a major possible single point of failure. It dies and your entire network goes down. While merely inconvenient for the kids coming home after school to play World Of Warcraft, it’s a whole different kind of failure if you’re a full-time home office worker who relies on internet access to be effective in your job.
