The Diesel Factor: Europeans are mad or Yanks are wimps

At the conclusion of this weekend's awesome running of 24 Hours at Le Mans, one conclusion was inescapable: Diesel engines rock! As Audi and Peugot battled for leadership in the P1 class during 24 hours of racing--lapping the curvaceous 8.5 mile racetrack at speeds averaging around 145 mph--it was clear that diesel engines are superior to their gasoline counterparts in many ways.

(P1 is open to gas or diesel power, so the fact that diesel-powered cars took the top 5 spots in this classic endurance race is pretty conclusive--although Toyota deserves an honorary mention for powering the Rebellion Racing Lola, the highest finishing petrol-powered P1.)

Mechanically-speaking, victory for the Audi R18 was particularly sweet in this, one of the closest finishes in the history of a race that was first run in 1923. For this was the first Le Mans endurance outing for this Audi engine, a 3.7 litre V6 turbodiesel that produces a whopping 540 bhp and features several design innovations, like a single turbocharger, sitting between the cylinder banks (versus a more traditional twin turbo setup, with one turbocharger per bank of cyclinders).

So diesels rock, and in Europe you can buy just about every model of road car, including Jaguars, Mercs, BMWs, Jeeps and Cadillacs, with a diesel powerplant. But not in America. Why? Because some states, like New York and California, think diesel cars are bad for you.Which leads us back to the headline: Europeans are mad or Yanks are wimps.

In other words, the people who govern New York must believe the Europeans are killing themselves by allowing diesel engines in cars. Californians must regard the steady rise of diesel engines to dominate the family car market in countries like Germany, France and the UK, as sheer madness, a total failure of public health and safety. There is no other way to explain the banning of something that is booming elsewhere in the world.

Maybe California should sue the U.K government for endangering the lives of tourists from California who visit London and other cities that are infested with diesels. Why pick on London? Well now that London uses traffic metering the city center is full of diesel buses and diesel taxicabs (yes, all London cabs are diesel and have been for ages). Or perhaps New Yorkers who attended the last royal wedding can start a class action suit and against the City of London.

Alternatively, the diesel-hating states of America could admit that a ban on diesels is totally absurd and reverse course, thereby ushering in a new era of reduced dependency on foreign oil. Yep, like that is ever going to happen.

Millions of Americans Lack Access to Broadband's Economic Benefits

"America may have invented the Internet, but more than 100 million American lack access to broadband and its accompanying economic benefits, according to a new report from the Federal Communications Commission.

Some 26 million Americans in largely rural areas across the nation lack high-speed connections to the Internet, the FCCs Broadband Progress Report to Congress found, cutting them off from broadband-based jobs and other economic opportunities."

Great Blog to Follow: Cassandra Heyne's Rural TeleCommentary

A wealth of detail on current discussions in rural telecomm regulation, policy, etc., from someone who 'gets' the value of rural broadband:
"Yet, people do live in these areas, and they deserve quality and affordable broadband. I have long argued that these are the people who need broadband the most, because broadband has the potential to transform their lives in ways that it cannot in urban areas simply by opening up the entire world of education, health care, finance, business and culture to individuals who would normally have to drive 300 miles to reach the nearest 'city' to conduct business or even purchase everyday goods and services." -- Cassandra Heyne

Give Back a Bit: Fixing the "Read More" problem in Blogger posts

I just found a problem in Blogger with the Read More jump feature, then I fixed it thanks to some helpful souls out there on the internets. You can see the thing I'm talking about if you view this post on the home page of the blog. The first part of the post appears on the home page of the blog but the rest of the post is not visible until you click the link that says "Click here to read the rest of the story..."

This was just not working on this blog before I fixed it today. The link, referred to as a jump and often denoted by More or Read more, did not appear, so there was no easy way to get from the home page to the rest of the story (you couldn't even see that the rest of the story existed).

Apparently this problem exists with some Blogger templates and not others. Using Google I found a solution and it is listed below the jump on this story. I wanted to thank the person who wrote the fix but his blog seems to have disappeared, so I am repeating the fix and thanking "swathipradeep," whom I assume is Swathi Pradeep, for coming up with this code and sharing it.

If you are having this problem with your Blogger blog then here is how you fix it (instructions created by Swathi Pradeep):

1. Back up your template code by downloading it: Go to the Design tab and select Edit HTML, then click Download Full Template. Save to your hard drive. This allows you to get back to the original template if something goes wrong.

2. After backing up your template, click the Expand Widget Templates check box (or tick the tick box if you're a Brit). Now scan your HTML for the following snippet (I used the Ctrl-F shortcut for Find):
<data:post.body/> 
Once you've located that code, paste the following snippet directly below it:
<b:if cond='data:post.hasJumpLink'> 
<div class='jump-link'>
<a expr:href='data:post.url + "#more"'><data:post.jumpText/></a>
</div>
</b:if >
As I have said before and will probably be saying again: I feel like I don't give back enough when it comes to the zillions of tech tips like these that I need/find/use to do my work/play. So I'm going to try to do better. I came up with GeeBaB as an acronym for Give Back a Bit and I will endeavor to geebab more useful tech learnings in the future.

Ironically, I ran into a problem trying to present the above tip because of Blogger's rather primitive display of code text. How did I get around the problem? I read about a dozen web pages offering solutions and decided the best one was these boxes to display code, as described in this post at BlogKori, Thanks!

Satellite Internet Whitepaper Downloaded Hundreds of Times Already

The launch of the RuMBA whitepaper addressing satellite Internet's suitability for rural broadband access has been going very well  with hundreds of people downloading it already. Here are some of the places on the web that the paper has been hightlighted:

Satellite Broadband Little Help To Rural Areas, Report Says

The new whitepaper is getting some traction in the press. You can download it from here. The following is from an article at ConsumerAffairs.com:

"Given the limitations of satellite Internet service detailed in this report, RuMBA cannot consider satellite a viable solution for rural communities who are increasingly cut off from mainstream America by the lack of access to affordable broadband service," said Luisa Handem, founder and Managing Director of RuMBA USA.

Reasons Why the Word Broadband Matters: #17 Satellite is not broadband

With over 610,000 subscribers, HughesNet is the largest supplier of satellite Internet service in America. The billion dollar company that owns HughesNet is Hughes Network Systems, LLC, which routinely describes itself as "the world's leading provider of broadband satellite services." You can see this on the company website and in the company's reporting of its first quarter 2011 results.

The problem is that broadband satellite is an oxymoron. The Internet you get from a satellite is not broadband. Just ask anybody who has used both satellite and cable, DSL, or fiber. The broadband functionality that DSL/cable/fiber users take for granted just doesn't work, or doesn't work well, over satellite; we're talking core functionality like automatic software updates, VoIP, VPN, NetFlix movies, website hosting, online backup and shared cloud storage services like Dropbox.

Who says such functionality is not there? The satellite Internet companies themselves, including Hughes. This fact is made clear in a 22-page report just released by the Rural Mobile and Broadband Alliance. Conveniently known as RuMBA USA, this non-profit group seeks to expand the availability of affordable broadband access in rural America.

Although I recommend reading the full report (disclaimer: I wrote it) you really don't have to look any further than the HughesNet website to see what I mean when I say that...

...the word "broadband" matters. The title of the website is: "HughesNet Hi-Speed Satellite Internet Provider." And the site describes a variety of services, all of which are described as high-speed Internet. None of them are described as broadband.

Now switch to the Hughes website and you will see a video titled "Consumer Broadband: A Thriving Market" and plenty of other "broadband" messaging. So why does Hughes talk "broadband satellite" on its corporate website and "hi-speed Satellite Internet" on the HughesNet consumer site, the site that actually sells the satellite service? The answer might be as simple as "truth in advertising."

You can't really fault HughesNet for saying "Enjoy easy, convenient high-speed Internet anywhere, anytime, Get High-Speed Satellite Today!" Based on 2 out of 3 critical speed factors used to describe Internet connectivity, HughesNet satellite Internet service can perform faster than a dialup modem. Indeed, adverts for the service often stress that is it faster than dialup. Headline upload and download speeds offered by the satellite service are certainly higher than the 56Kbps at which a dialup modem maxes out.

Where satellite Internet is not faster than dialup is the time it takes for a single bit of data to get from one computer to another across the network. This is known as latency and it has a big effect on things like signing into your online account and other secure services over the Internet (basically any web page URL that starts with https://). That's because encrypted connections require a "handshake" to take place in which a lot of small pieces of information are exchanged back and forth between the web server and the web client.

You can read more about security handshakes in this 2002 USENIX security paper. But latency affects more than secure connections. The time between sending a request for a web page or a change on a web page and the time that the request reaches the server that is serving up the page is always going to be longer over satellite, about 10X longer than on a true broadband connection. See this early paper that references the problem: Data Coomunications Protocol Performance on Geo-stationary Satellite Links (Hans Kruse, Ohio University, 1996).

As Kruse states, the one-way trip for a data bit to a geo-stationary satellite takes 250 milliseconds (that's 500 for a round trip into space and back). And the laws of physics dictate you can't shorten that time, unless you can get data packets to travel faster than the speed of light. Add some ground station and Network Operations Center overhead and you get a best case satellite Internet latency of around 600ms. This might not sound like a long time but it can mean that logging into a secure site can take minutes, not seconds.

Other activities, such as a typical remote employment task like writing code, are also impacted. Consider this programmer's complaint about cable Internet being slower, at 80ms, than DSL at 20ms. Now compare that to 600ms, which is the best I've seen on satellite, where latency can average 1000ms, or 50 times slower than DSL.

So, satellite is not broadband, and that matters because the federal government has given tens of millions of taxpayer dollars to satellite companies to provide broadband service. As the Hughes Annual Report of 2010 proudly proclaims: "Hughes Wins $58.7 Million Under U.S. Recovery Act Broadband Program." Except it just isn't broadband.
