No Citywide WiFi Network For Chicago

This is one more rethink of the citywide WiFi concept.

WiFi logoAn ambitious plan to blanket the city of Chicago with Wi-Fi internet access was scrapped this week, primarily due to cost concerns as well as the lack of a proven business model for citywide Wi-Fi.

“We realized, after much consideration, that we needed to reevaluate our approach to provide universal and affordable access to high speed Internet as part of the city’s broader digital inclusion efforts,” said the city’s Chief Information Officer, Hardik Bhatt, in a statement Tuesday.

The proposed network would have ultimately covered Chicago’s 228 square miles with wireless internet access, through one or more private-sector partnerships. Negotiations with potential partners have stalled in recent months, however, due to the realization that a citywide network would require massive taxpayer financing to get off the ground.

One of the companies negotiating with Chicago was EarthLink, an Atlanta, Georgia-based ISP, which has already won several municipal Wi-Fi contracts and deployed a number of networks across America. This summer, EarthLink said that it planned to better study the performance of its current municipal Wi-Fi networks before embarking on any additional projects.

“We’re seeing this evolve as we learn more about these networks, and the city needs to think about this again from its own business perspective,” said EarthLink’s vice president of municipal sales, Tom Hulsebosch, in an interview with the Chicago Tribune.

All is not lost of Chicago wireless broadband enthusiasts, however, with the city set to house one of America’s first citywide WiMAX networks. Cell phone carrier, Sprint Nextel, has announced that Chicago will be among the first three markets for its forthcoming WiMAX broadband network.

WiMAX works along similar principles to Wi-Fi, but is much more efficient, potentially blanketing whole municipalities with broadband internet service from a single base station.

Buick V8 Powered Chainsaw

Buick V8 Chainsew pictureMy grandfather, Hans Peter Olsen, went to work in the lumber woods of northern Michigan when he was twelve years old. He left the woods as a teamster at age eighteen, returned to Mason County, and purchased an 80 acre farm with his saved earnings.

That said, I don’t see how he could have imagined anything remotely like this thing. They call it the Preditor. It is a chainsaw powered by a 215 cubic inch Buick, aluminum block, V8 that might have been built here in Flint. Bring on the redwoods, baby.

A Podcaster’s Teleprompter

Podcast Autocue screen shotIf you have ever tried to read from a sheet of paper in front of a microphone you have no doubt discovered that there are potential problems. First, there is the noise caused by the proximity of the paper to the microphone. Second, is the possibility of phase distortion caused by your voice being reflected back from the paper along with the direct sound.

Professional broadcasters learned decades ago that the solution is the use of a teleprompter, also called an autocue. Unfortunately, the hardware versions are expensive. An inexpensive solution is to use a freeware or shareware computer software based prompter.

One such is Podcaster Autocue 1.1. You can check out the manual for it online.

AllOfMP3: “The Service Will Be Resumed”

allofmp3.com logoFollowing a Russian court’s ruling that AllOfMP3 acted within the letter of the Russian copyright law - such as it is, folks - the site is promising to resurrect itself in the ‘foreseeable future’.

The site’s bog page says that “service will be resumed” and that work is going on behind the scenes to re-enable accounts, balances and music ordering services.

There’s no further details, but this seems like a fairly big deal for the record industry, which must have thought it had succeeded in getting the industry’s favourite big boogeyman taken out of play.

The problem comes because America made it quite clear that Russia couldn’t accede to the WTO without ditching the site, which the Yanks were adamant made a mockery of international copyright treaties. Fair enough. So the Russians pulled it down - only to find that since they hadn’t actually acceded to the WTO yet, their copyright laws still meant that the site was legal, and a judge ruled as such.

It now seems that for the site to be pulled down for good, someone in Russia is going to have to hastily enact some decent copyright legislation - not an easy task.

Satellite Alignment Calculator

Satfinder imageHams using satillite dish antennas will appreciate this tip.

Hackszine reader Alan writes:

Anyone who ever installed a satellite dish knows how frustrating it is to point the dish at the satellite somewhere in the sky. I’ve created a unique tool which calculates the dish angle based on user location and then draws a line on the Google Maps satellite image. You can actually see your house, mark the dish position and then see where to aim the satellite dish.

I’ve tested it on many installations and the accuracy is amazing, it gets it spot on.

The site is a UK site but the tool works world wide for any satellite and any location. This is a genuinely useful tool for a lot of people.

This is pretty neat. In addition to just drawing a line on the map, you can see how far the satellite is from your location and what the proper elevation angle should be on the dish. This could be useful for determining the nearest or least obstructed satellite for your home.

Software Bug Took Out Skype

Posted by Bob Olsen on Friday, August 24, 2007 at 11:36 am

It looks like the mystery of why almost everyone’s favorite Voice Over IP system went down last week has at last been solved.

Skype update screen shotSkype today provided a few more information pieces about the reasons behind its massive network outage last week. According to the company, the network outage was initially caused by a “massive restart of [its] user’s computers across the globe within a very short timeframe as they rebooted after receiving a routine software update.” That high number of reboots was followed by an equally high number of log-in requests, which resulted in what Skype calls a “chain reaction.”

On the Skype blog, a company representative wrote that this event revealed a “previously unseen software bug within the network resource allocation algorithm” which prevented Skype’s “self-healing function from working quickly. … Skype has now identified and already introduced a number of improvements to its software to ensure that our users will not be similarly affected in the unlikely possibility of this combination of events recurring.”

The company said that there were no malicious activities that impacted Skype.

The DIY Segway

Posted by Bob Olsen on Wednesday, August 22, 2007 at 11:29 am

DIY SegwayA group of students from Wayland High School, John D. O’Bryant School of Math and Science, and Cambridge Rindge and Latin School working with four MIT students have built a self-balancing scooter like the Segway™ for less than a thousand dollars. The thing actually works, as demonstrated in the video.

The parts list for the student’s version is much less sophisticated than that of the Segway’s. The students used sheet aluminum, Lexan, a PIC microcontroller board connected to a laptop used for programming and debugging and other very basic parts. All of the code on-board the DIY Segway was written in C.

The students have a web site that gives further info about the project. I love the Port-A-Pottys in the background in their publicity stills.
