Philadelphia City-Wide WiFi

April 12, 2005


One of my 2005 VoIP Predictions seems to be a step closer to becoming reality. I wrote:
____________________________________________

8) Cities become their own phone companies
You will start to see more cities not only offering high-speed wireless broadband using WiMAX and other high-speed wireless technologies, but you will start to see cities offering their own phone services as well. Just think of the loyalty they can build! If I have my choice between paying a private VoIP company based in New Jersey versus paying my local town, heck I'll give the money to my local town.




Google Local Mobile Search

April 12, 2005

Google launched a version of Google Local that’s specifically designed for cell phone browsers PDAs, or Smart Phones such a the popular Treo 650. It's similar to Yahoo’s mobile local search, but the integration with Google Maps is pretty cool. Google Local mobile search is pretty simple to use, you simply key in your search term as well as location or zip code and Google sends back a nice compact, mobile-screen-sized Google Map. As with all things Google, this info is free of charge - the one exception is if you pay Google to display Google Ads of course via their Google Adwords program.

MoCA 100Mbps over Coax Trials

April 4, 2005

While DSL technology has steadily improved resulting in an increased distance from the CO and increased bandwidth, for instance, ADSL2+ has 25Mbps downstream, the news about coax cable improving its throughput has been notably absent - until now. The Multimedia over Coax Alliance (MoCA) is announcing the successful results of its large-scale field trial at the National Show (see release below).

Conducted by MoCA's founders in 15 cities, the trial validated performance of 100 Mbps in real world condition over typical coax cable. Most highspeed broadband solutions over coax solutions, such as Charter's High Speed Internet max out at 3Mbps or roughly 33X times slower than MoCA. These results evidence MoCA's capabilities as both the highest-speed technology for home networking, and according to MoCA's founders, the only technology field-proven to be capable of transporting multiple HDTV streams.

MoCA's founders are Comcast, EchoStar, Entropic Communications, Motorola, Cisco/Linksys, Panasonic, Radio Shack, and Toshiba.

Here's the release:

MoCA Concludes Successful Field Trials for Home Networking of Digital Entertainment Using Coax

-- Large-scale tests validate performance of 100 Mbps in real world conditions

San Francisco, CA-April 4, 2005- Multimedia over Coax Alliance (MoCA) today announced a major step forward with the completion of successful field trials of the core technology to provide networking of digital home entertainment throughout the home on existing coax cabling in cable homes at NCTA - The National Show (Booth 6490 - CableNET).











Skype + Blog = Next Bill O'Reilly?

March 28, 2005

So you wanna be a journalist eh? Well, these days, just start a blog and you're good to go! Unless of course you're Apple and you don't classify bloggers as journalists. (See Apple suit against blogger) In any case, the good bloggers tend to be great writers and researchers - traits of any good journalist, but do they have the verbal interviewing skills of a no-nonsense, go-getter journalist hound?

RFID to Identify "Hit and Run" Perpetrators?

March 28, 2005

Now here's a scary thought. This website: "www.RFID2VIN.com" proposes the use of RFID chips that would be left at the scene of "hit and run" accidents. According to their email to me, these unique identifiers would then act as a sort of "automotive DNA," providing the registration information for that particular vehicle.

I perused their website very quickly (could use a web designer IMO) and it appears this involves embedding RFIDs in the paint, bumpers, headlamps, etc. Then when you get into an accident, the RFIDs are dislodged and left at the scene which can be used to determine the car's position at the time of the accident to determine fault, as well as whose car it is in the event of a "hit and run".

I'm sure the ACLU will be all over this...





DNA Backup Surprises Scientists

March 23, 2005

Scientists have apparently found a "backup" to our DNA. According to the journal Nature, one plant was able to revert to genetic code that doesn't contain a genetic mutation that its parents had, (using a previously unknown "backup" copy method), and it reverted to the genetic code of its grandparents. The authors of the paper theorize that the backup may reside in molecule RNA somewhere and that stress may trigger the genetic reversion. If this turns out to be true in humans as well, not only will we have to rewrite the genetic textbooks, but this could lead to cure of diseases caused by genetic malformities.

According to the article, the finding challenges textbook rules of inheritance, which state that children simply receive combinations of the genes carried by their parents.

MovableType Aggregation

March 18, 2005


I'm playing around with some aggregation on my blog. I'm hoping to include excerpts of some interesting stories from outside news sources, blogs, etc.

You probably already noticed a few on my home page already. It took me a few days of some Perl coding - actually deciphering other people's Perl code, getting the proper modules installed into ActivePerl, drinking a few extra cups of coffee and diet Coke, and banging my head against the wall, but it finally works!

I still have some tweaking to do, but my goal is to bring important news information from outside sources into my blog.


Subscribe to MovableType Comments

March 16, 2005

Well, I had some visitors to my blog request the ability to "subscribe" to comments so they know if someone responds to a comment that they posted. Or if they are just interested in a thread they can even subscribe to comments on a particular blog entry.

I spent a good portion of yesterday trying to get the EZ Subscribe plugin for MovableType to work - only to find out the plugin is no longer being developed or supported. My background is in programming, but MovableType plugins are in Perl, which is not my forte'. Fortunately, the developer of EZ Subscribe pointed me to another subscription-based plugin for MovableType called MT Notifier.

Photo License Plate, Tow Car, Get Delinquent Taxes

March 11, 2005


According to CNN, it looks like my home state, Connecticut, is employing technology to snare car propery tax delinquents. City marshals in cash-strapped New Haven are armed with a tool called BootFinder that photographs auto license plates and instantly matches them against a tax scofflaw database. Once they have a match they tow the car away - doesn't matter if it's sitting in your driveway or a Walmart parking lot. I always pay my taxes, but this technology has some scary implications.

What really surprised me from the CNN article I read about this is, "Connecticut is among a handful of states where local governments levy annual fees, typically a few hundred dollars per vehicle, based on the value of residents' automobiles."

You mean to tell me that not all of the U.S.




Vetrix VXe Scooter

February 28, 2005

I just received this interesting email about an interesting electric scooter.



I was wondering if you could help get the word out about a revolutionary new EV that will be released in 2006. It cruises at over 60mph and goes up to 70 miles on a single charge-34 cents would be the national average electricity cost. Of course, no noise or emissions. The website is www.vectrixusa.com, and here's an insider image of the bike's new design.
