As mentioned in my previous Garmin Forerunner 405 post, I was skeptical of the "upgrade" a Forerunner 405 represented when compared to a Forerunner 305. As I suspected, the 405 should not be considered much of an evolution in the product line. Most of the enhancements are superficial, and fail to make the product more functional. Unlike the giant leap between the 205 and 305, the 405 is simply a disappointment. Melissa has had one since its release, and posts her Garmin Forerunner 405 review on her blog. Needless to say, I'm sticking with my tried and true 305.

Internet Fraud.

I've always heard about rampant Internet fraud, but I've only ever personally encountered it in two occasions. For the most part, Internet transactions are safe and free of fraud. The ones that are fraudulent seem to be fairly easy to catch. This one was caught and brought to my attention by a smart individual who ran across an advertisement for "Adorable English Bulldog puppies" [link]. Liking adorable English bulldog puppies [who doesn't], the individual inquired further and requested to see the pedigree. The pedigree delivered via e-mail was a poorly modified version of my dog's pedigree, originally posted on this very blog. I've posted the faked pedigree for comparison.

The wonderful thing about the Internet is that you can do a little bit of work to connect the facts and uncover possible fraud. Tapas' breeder was contacted by the above-mentioned individual, after they did some research on the lineage. The obvious question was, "How could an English bulldog come from a family of Chihuahuas?" I'm just curious as to why the fraudsters swapped out the American Kennel Club logo and changed the typeface at the top of the certificate -- both seemingly unnecessary steps to take.

Don't think that I am trying to downplay Internet fraud. It's a very serious problem with very few solutions. In fact, posting this entry is one of the few responses available to me. So,...let it be known that the individual(s) using the name "filly mimi" (fillymimi@live.com, fillymimi@aol.com) may try to sell you a fictitious bulldog pup. They are probably running the same scam with other names, e-mail addresses, and dog breeds. Be cautious! The common thread in their particular scams will probably be their poor grammar. See below:

I hate to say it, but this has the stench of a Nigerian scam.

Garmin Forerunner 405.

After almost two years since the release of the Forerunner 305, Garmin has finally announced the release of an upgrade in their line of personal fitness computers. A comparison of the two models makes me think that the main difference between the 305 and new 405 is the form factor. The 405 does sport a new, wireless sync capability (using an included USB ANT™ stick), but I never felt that the older USB cradle represented an inconvenience. In fact, the combination of sync and charge in the older USB cradle was really great for traveling. The 405 will require carrying the "stick" and a separate charger. Is that an upgrade?

In all honesty, it is unfair to make an assessment by comparing manufacturer specs -- especially if the products are from the same manufacturer. For whatever reason most manufacturers have an uncanny inability to convey their products' key value propositions. Take, for example, almost any PC laptop maker (e.g., Dell, HP, and Sony). Can you tell the difference between a Dell Vostro™, Latitude™ or Precision™? It's like a exercise in graph theory every time you want to make a purchasing decision. But I digress.

The Garmin Forerunner 405 could be a quantum leap in the Forerunner evolution, as the 305 was to the 205. I won't know until I actually own one and can make a "real world" judgement. The catch is that I'm not compelled to upgrade, yet. Somebody else needs to be the first penguin in the water this time. Unless, that is, Garmin wants to send me an evaluation unit.

Traveling Internationally with the iPhone.

nospam@example.com (Richard D. Huff) — Wed, 13 Feb 2008 10:02:15 -0700

You've all heard the stories about thousand dollar phone bills when traveling internationally with an iPhone. As someone that once sent a very costly e-mail (~$1,900) via my Cingular 3G wireless Internet service while roaming in the Pisa, Italy airport, I can attest to a valid concern about mindlessly roaming with an iPhone. Although I already had the discounted international roaming package ($5.99/month) for my voice service, it does not cover any of the data service that is so important to the iPhone. Enter AT&T's "Data Global Plans for iPhone". At just $24.99/month, you can head off most of the scary data roaming costs associated with using the iPhone internationally. Thirty-six countries are covered in the plan, and you can start and stop the service at any time (i.e., there's no new contract associated with the feature).

The Need For Network Speed - Part II.

nospam@example.com (Richard D. Huff) — Sat, 7 Apr 2007 15:52:53 -0700

Between 1998 and early 2000, analog dialup started to slowly slip as ADSL and cable services were deployed. There was no doubt that faster, full-time connections were needed for both homes and businesses. After all, these were the heady days of the dotcom bubble. Telecom companies and cable providers were just not deploying services quickly enough. It's no conspiracy theory that telecom companies didn't want to provide the service because it threatened to undermine an existing business, and that cable companies had quite a bit of network upgrading to perform before wide deployment could even occur. Furthermore, both ADSL and cable were -- for the most part -- the purview of the incumbent telecom and cable companies. Internet Service Providers, try as they may [1][2], didn't have a chance in these markets.

The dotcom crash, 9/11/01, and the telecom scandals didn't help things. What did occur following those disruptions was the popularization of Wi-Fi (IEEE 802.11). Also, the value of the Internet barely skipped a beat. E-commerce, digital music, voice-over-IP and video were almost entirely grass-roots movements, driving the necessity for bandwidth ever higher. Podcasting, video blogging, and television distribution through Apple's iTunes are happening today -- not at some distant future time. The ADSL and cable bottlenecks are the dilemma that continue to constrict progress.

Without touching on the distinction between theoretical and real bandwidth, let's continue the relative network speeds graph from Part I of this post.

Although both ADSL and cable services have begun to deliver faster speeds, they're both dwarfed by the network performances most of us experience every day in our home and office environments. Furthermore, they are not technically different from the ADSL and cable services provided in 1998 -- they're just much closer to their maximum potential. To put my point into greater relief, the following graph presents a comparison between the connection speeds of my actual networks as I write the post.

The server where my blog exists is in a data center next to Seattle's Space Needle. It connects to the physical Internet via a full-duplex, 100 megabit per second Ethernet port. My office has both an 802.11g Wi-Fi access point (half-duplex, 54 megabits per second) and a full-duplex, 100 megabit per second Ethernet network. The fastest Internet connection I could have installed at my office -- without paying several thousand dollars per month -- was 7 megabit per second (down) by 1 megabit per second (up) ADSL. Most people don't even have that fast of a connection.

With the growing popularity of gigabit per second Ethernet and the new 802.11n Wi-Fi specification, the disparity will only grow.

In summary, new Internet applications such as podcasting, music and video distribution are continuing to necessitate higher network speeds. Whereas local area networks based on Ethernet, fiber and Wi-Fi regularly operate at speeds between 100 and 1,000 megabits per second, telecom and cable companies have reached the end of their bandwidth potential using the existing copper and coax infrastructure. A move to ADSL2+ or Hybrid-Fiber-Coax will not be enough to address this ever-increasing disparity. Part III of this post will explore possible futures.

The Need For Network Speed - Part I.

nospam@example.com (Richard D. Huff) — Sat, 7 Apr 2007 00:04:49 -0700

In the early days of commercial Internet access -- when I ran a regional Internet Service Provider in Washington State -- the primary service was analog public switched telephone network (PSTN) connections at 14,400 bits per second, 28,800 bits per second, and 33,600 bits per second. The 57,600 bit per second analog modems, introduced in 1996, exhausted the bandwidth capability of the traditional voice network. In fact, it was the first time in which a large proportion of the connections could not reach the maximum performance rating.

During this "analog age", there was also a great battle waged between providers that sold a metered service and providers that sold a flat (a.k.a., "unlimited") service. The main limitation for both types of providers was that they didn't achieve a 1:1 ratio of PSTN ports to customers -- doing so would have been both cost prohibitive and, essentially, impossible. Contrary to what you might imagine, however, the challenge in deciding which camp a provider should belong was not related to determining an appropriate port-to-customer ratio through a distribution analysis of past call frequency and duration. This would have been totally inadequate in light of the dramatic change in usage patterns occurring month after month. Instead, the providers selling an "unlimited" service were making a losing bet.

It didn't take a Nostradamus to predict the future, as the Internet shifted from a primarily text environment (E-mail, Telnet, Gopher, FTP, et al.) to one that included graphics and multimedia (HTTP, RTSP, etc.). Call frequency and duration skyrocketed. The new features not only demanded more bandwidth, but also increased the number of reasons people might want to connect. There was a rapidly growing desire for high-speed, full-time connections to the Internet, and the public switch telephone network was not a good fit.

The analog voice network, however, was so pervasively installed that "technologies" even started to appear for bonding multiple PSTN lines. These connections were almost always assumed to be full-time as well. Although bonding analog connections never really took hold as a viable practice, it's important to realize how much momentum is generally behind squeezing capability from a ubiquitous network. This brings us to ISDN.

We began selling ISDN connections in 1995. The same copper wire pairs used for delivering PSTN circuits can, in most cases, deliver an ISDN circuit. An ISDN Basic Rate Interface (BRI) delivers up to two 64,000 bit per second digital channels. Most ISDN equipment can bond the two channels, for a maximum of 128,000 bits per second. ISDN, however, operates on the same "switched network" paradigm as PSTN. As a technology for delivering high-speed, full-time Internet service, it was nothing more than a flash in the pan. Asymmetric Digital Subscriber Line (ADSL) and cable Internet service overtook ISDN by the end of 1998. Both ADSL and cable service provided faster, full-time connections to the Internet.

During this same period, it was popular for businesses to purchase dedicated Internet connections at rates between 56,000 (DS0) and 1,544,000 (DS1) bits per second. Although these full-time, digital circuits used the same sort of copper wire pairs (or pairs of pairs, as is the case with DS1) that analog voice circuits used, they were separate from the public switched telephone network. The very maximum Internet connection speed that most businesses could financially justify between 1995 and 1998 would have been the DS1, costing between $1,000 and $2,000 per month. Only the largest organizations and Internet Service Providers purchased circuits larger than a DS1, and I only mention them here for comparative purposes.

In summary, the early growth of the Internet saw a rapid shift from part-time connections based on the analog PSTN to full-time connections based on the much faster DSL and cable services. The demand for faster, full-time Internet connections resulted from the growing benefit derived from its use. Part II of this post looks at the period from 1998 to the present.

Seattle's CTTAB.

nospam@example.com (Richard D. Huff) — Tue, 27 Feb 2007 12:48:06 -0700

This year marks the beginning of my two-year appointment by Greg Nickels, Mayor of the City of Seattle, to the Citizens' Telecommunications and Technology Advisory Board (CTTAB). The board advises the Mayor's office and the City Council on technology and communications issues facing Seattle. Although my background includes a variety of technology competencies, my primary contribution will likely be with the committee consulting on Seattle's Broadband Initiative. Watch for the new FTTx (Fiber To The Home and Fiber To The Premises) category on this blog to follow developments over the next couple years.

PODRUNNER: Music For Your Race.

nospam@example.com (Richard D. Huff) — Fri, 9 Feb 2007 11:27:18 -0700

Melissa -- now the proud owner of an 8GB iPod Nano (Product)^RED -- turned me on to the best workout mixes I've ever heard. DJ Steveboy mixes hour-long tracks of 130 to 180 beat-per-minute ear candy. It's the sort of music that makes you want to throw up your arms and dance while you run. Not even the music from Rocky touches the sort of nerve that PODRUNNER tracks tickle. Take a dose for your next run.

You can get it through iTunes:
