Revisiting Steve Song & The Village Telco

You may recall that some time ago we had Steve Song appear as a guest on a VUC call. At that time he was working for the Shuttleworth Foundation coordinating the Village Telco project.

The Village Telco project developed a low-cost hardware device intended to help deploy telephony to underserved parts of Africa. This device, called a Mesh Potato, is essentially a wifi access point with a built-in analog terminal adapter. Groups of Mesh Potatoes form a wifi mesh network. This supports the sharing of voice & internet resources at extremely low-cost compared to commercial solutions.

Wrestling With a Definition Of “The Cloud”

For much of the past year I find that I’ve been struggling with putting some definition on “The Cloud.” This thought process began way back on November 5, 2010 when I hosted a VUC call that was a panel discussion intended to consider “The Cloud” in its many facets. That call featured a number of guests, each of whom had specific experience with cloud infrastructure, applications and services. Since that time I’ve been pondering what was said, and further, the evolving public perception of “The Cloud.”

So it was that while attending ITExpo earlier in the month I found myself spending much of my time there in the sessions that comprised the CloudComm Summit 4. During those sessions I had the opportunity to pose some of my questions to the assembled experts. In some cases their answers were enlightening, in other cases they seemed to be puzzled about the very nature of the questions. Even so, all of this has helped to crystallize my own personal definition of The Cloud.

One of Microsoft’s more recent marketing programs made considerable mention of “reaching for the cloud,” presumably with respect to some common end-user applications. I can’t help but feel that such public representations are less than helpful, perhaps even a little misleading.

The Fastmac USocket Revisited

FastMac-USocket Some time ago at Engadget there was a post reporting that Fastmac was about to start shipping their much delayed USocket. The USocket combines a normal wall electrical outlet with a DC power supply that feeds a pair of standard USB ports. Further, each port provides enough current to charge even heavy loads like Apple’s iPad.

I though that this device sounded like a great idea so I visited the companies web site and ordered four. That would let me put one at each night stand in the bedroom, one in my office and another in our TV room.

Near the end of January I placed the order then waited for delivery. In fact, I forgot about the order. When in mid-May I finally remembered that I had placed the order I filed a trouble report with Fastmac to inquire about its status.

The company literally never responded to my trouble report. Instead, they simply shipped the order. I did receive an email notice that the order had been both billed and shipped. Given their behavior I doubt that I’ll ever buy anything from them again.

Telecom Continuity Strategies in the Cloud Era: SOHO Edition

As you likely heard on April 27th Northern Alabama suffered a spate of violent storms, including a number of large tornados. Many thousands of people were impacted, including long term loss of power and network connectivity. Digium was amongst the many, many businesses impacted by the events of the day.

I must commend Danny Windam, CEO of Digium, for making excellent use of the corporate blog to keep the Asterisk community informed about the companies operational status. Some time having elapsed since the unfortunate events of that day Digium has since returned to normal operations.

When The Wifi Blows: Experience At NAB 2011

The past week or so my attention was wholly consumed by the annual convention of the National Association of Broadcasters. Held in Las Vegas each April the NAB exhibition is the major event in the year of a broadcast equipment maker. This was my 18th NAB, which makes the more a test of stamina than anything else.

Happily, the show was for my employer a considerable success. Attendance has returned to reasonable levels. It seems that broadcasters are feeling better about their existence. Globally broadcasters are starting to move forward with long stalled projects. New channels will be launched and existing services enhanced. It all bodes well for the manufacturing sector of the industry, presuming that manufacturers have toughed out the recent slow period and continued to develop products that improve the operating efficiency of customers.

For our company the one major annoyance of NAB 2011 was the complete failure of wifi on the show floor. From the last day of setup to the close of the event wifi was essentially useless. This was not a huge problem, but a considerable inconvenience. In our case it meant that the many sales and executive staff present could only access email via a wired network connection.

A Tale Of Wonky Wifi Part 5: Another Transition

Open Mesh OM-1P Wireless Access Point When last we left our intrepid hero he had suffered nine months of unreliable Wifi wound the home and home office. After trying a major brand name SMB class 802.11N type, which was utterly disappointing. At the end of part 4 in our saga we had just completed the installation of a pair of Open Mesh OM-1P 802.11G type MESH APs. Beyond that the entire project went quiet.

In this case that long quiet stretch is “a good thing*.” The OM-1Ps were in service for over a year. I had one in the house in the forward portion of the property and a second in the office at the rear. Two were required to provide adequate coverage.

The OM-1Ps were not perfect. They were only 802.11B/G, so lacking some of the features of newer N-type APs. Also, they didn’t support WPA2 encryption, which would have been my preference. Still, they worked well enough that I left them in service.

After about eight months the OM-1P in the house started to become unreliable. After resetting it a few times I simply powered it down permanently. That meant that wifi coverage on the front porch was sketchy to unusable.
