Notes From The Road: Kensington Replacement Power Supplies For Laptops

This past weekend, during a break from tending our new pup, Stella and I had occasion to see the movie Up In The Air. I’d not seen it before, at least not from start to finish. Now that I have seen it, I think I understand why some members of my family thought that the film reminded them of me.

It’s true that I am something of a corporate road warrior. That is to say, my job involves more than the occasional bit of travel. Since the beginning of the year I’ve been to Las Vegas, New Jersey (twice), South Bend IN (twice), Jackson MS, and Berkeley CA. As I write this I am in fact en route to Charlotte NC to give a three-day training course.

As The Beach Boys once harmonized, “I get around.” Further, I’ve been in this line of work for just over fifteen years.

All of that only serves to illustrate that I have at least some experience being on the road. In that time I’ve come to appreciate some relatively simple pieces of technology. Occasionally a modest little item, perhaps acquired by accident or mere happenstance, can actually improve your quality-of-working-life on-the-road.

Notebooks, Netbooks & Tablets…Oh,My!

This post is inspired by the recent release of the HP Mini 5103. I’ve been carrying its predecessor since April, and meaning to share my recent experience with netbooks, especially in the light of the coming onslaught of tablets.

There are aspects of my working life that lands me squarely in the category of “Road Warrior.” Business has me visiting customers locations all over North America, and occasionally locations overseas. This very fact of my routine travel has dictated that I carry a laptop. Remember that my employers business is broadcast graphics equipment, so our laptops are on the more capable side of things…meaning more powerful, bigger & heavier. Recently our staff have started carrying “mobile workstations.”

D.I.Y. Asterisk Appliances: A Question Of Scale

Selecting hardware appropriate for a particular Asterisk installation has been a topic of discussion ever since the emergence of Asterisk. This typically centers around choosing hardware to handle n users or x concurrent calls. Often the focus is on how to scale up to the greatest number of users for a given server. However, there can be different but related considerations as we consider ever smaller applications.

In various circles I’ve lately witnessed a minor spike in interest in small form factor Asterisk systems. I have found it curious to survey the various hardware platforms that people are considering when creating their own DIY Asterisk Appliances. To establish some perspective on this I recently posted my own history of using Asterisk my own little Asterisk retrospective.

There are quite a range of small computing platforms available to the enthusiast seeking to tinker with Asterisk. It seemed to me that an overview of such hardware and related resources would be helpful.


For my purposes I’ll only consider generic platforms suitable for a DIY project , not the commercially offered embedded Asterisk devices, of which there are many. These small host platforms tend to be in the $50-$300 range which makes them approachable for hobbyists, home users and some small businesses.

A History Of Asterisk In My Home Office

I’ve recently been reflecting upon my history as an Asterisk user and the evolution of my preference for embedded systems (aka appliance) approach to Asterisk servers.

The path that I’ve followed is probably typical of a lot of people in many ways. Perhaps by sharing my experience I can help some people avoid some of the problems that I have faced, and understand how I arrived at my personal definition of an “Asterisk Appliance.”

Deal Alert: HP Mini 5101 & 5102 Netbooks from $297!

The HP mini 5102 has only been shipping for a few months. I’ve only had mine for about a month. Even so deals are starting to show up.

These corporate class netbooks are head & shoulders better than the consumer offerings you’ll see at retailers. Today’s email list of overstock and refurbished systems from the HP SMB Outlet includes 20 different configurations of the 5101 & 5102…starting from only $297!

The SMB Outlet even have a number of systems that are not the Smart Buy configurations.The Smart Buy configs are kinda bland, but faster to ship. To get the more interesting options you had to order a custom configuration and have it made to order. This is why it took three weeks to get delivery of mine…and it cost just shy of $800.
