More NodeDB changes

Filed under: News & Events — evilbunny @ 5:38 pm

In the last lask couple of weeks I’ve added extensive code to NodeDB, I’ve also updated the digital elevation data to 3 arc second released by NASA, to produce much better quality elevation cross section images.

Below is an example of the difference in image quality as a result:

As a result of the upgrade I started out with example Google code, but this involved xml data files, but due to having arbitary data in the system caused the maps to break, so after much head banging I ended up replacing this code with much simplier HTTP/CSV data that won’t break if there is a stray & or the much more commonly & in html entities for multilingual entries.

Basically AJAX minus the xml is much better imho, it tends to break a whole lot less…

NodeDB.com receives major overhaul

Filed under: News & Events — evilbunny @ 4:04 pm

Today the new NodeDB.com website went live. This is the first major overhaul to the site in a few years, but is a welcomed change as it brings with it google map integration along with a whole host of improvements designed to make the site more usable and to take away some of the more interesting limitations.

Since the main reason for the change was to integrate google maps, it was thought a whole new approach should be taken with how the rest of the site operated.

Previously there were a number of limitations both due to my design as well as the original design by David and this left things separated into regions, which meant people outside of these regions weren’t able to add themselves until the region was expanded.

However using javascript based technologies has it’s own limitations and the big one is not being able to display all locations at the same time after about 150 to 200 locations browsers tend to run slower and with enough locations can fill the memory of the computer it’s running on and crash. The news isn’t all bad, as the missing locations show up as you zoom and pan across the map, and most likely the missing locations wouldn’t have been clickable in any case as the icons tend to overlap.

Currently only core functionality has been coded (signing up, adding, editing and deleting locations among other simple things) and as time passes more features will be added in.

If anyone is interested in $5 worth of free VoIP calls email me and I’ll give you details. Currently testing a new VoIP service and looking for people to abuse it as much as possible to see what breaks :)

Wi-Fi Policing Comes to Georgia

Filed under: News & Events — evilbunny @ 10:37 am

Sandersville, Ga., isn’t your typical sleepy town of the American South. Not only is it home to the governor, it is also a telecom-savvy city with a municipally-owned fixed wireless network — and now it can add a Wi-Fi-enabled police force to its list of innovations.

Less than a year after the non-line-of-sight network was installed, its designers at Atlanta-based Camvera Networks (formerly Tri-State Broadband Inc) have returned to install Wi-Fi connections in five police cruisers.

Faster Wi-Fi Handoff Arrives?

Filed under: News & Events — evilbunny @ 10:31 am

Wi-Fi client devices, such as a laptop computer, will connect to the strongest available signal. But when the signal degrades and data packets begin dropping, the client device sends out a SOS on all channels looking for another access point, a process that could take as long as one second.

In other words: sometimes the solid Wi-Fi connection linking you to the Internet turns to mist, and that broadband pipe you were relying upon becomes a soda straw. It is the times like these that two University of California computer scientists hope to banish.

Go-ahead Rev opens Wi-Fi church

Filed under: News & Events — evilbunny @ 1:37 am

A Cardiff vicar has addressed the problem of falling congregations by offering his flock a quiet wireless hotspot in which they can seek the meaning of the word salvation on Google while chewing the fat via email with Pope Benny 16.

Keith Kimber, of St John’s in Cardiff city centre, has sold his soul to Cardiff Council and BT Openzone to acquire the wirless technology. Before inking the mephistophelean technopact, Rev Kimber was unable to access the city’s wireless services due to his church’s four-foot-thick walls. Now, however, he boasts a wireless node within the body of the House of God itself.

Said the good Reverend: “The church has to move with the times and I wanted to make St John’s a sanctuary for everyone, including business people with laptops and mobiles.”

Hmmm. We feel he may have cause to regret that sentiment when his sermons - written on laptop, natch - are drowned out by the clackety-clack of dotcom yuppies banging away at mission-critical Powerpoint presentations and suits gibbering meaninglessly into 3G mobes.

In the end, what the church needs is less technology and more people genuflecting. And no, we don’t mean before an altar to Steve Jobs or Linus Torvalds.

VeriSign, Microsoft Plan for Wi-Fi Security

Filed under: News & Events — evilbunny @ 10:20 am

VeriSign says it is working with Microsoft on solutions to secure corporations with users who employ Wi-Fi at work, home or in public.

They are working together on a reference architecture that will be based on both VeriSign’s Unified Authentication (UA) and Microsoft’s Network Access Protection (NAP).

The purpose is to let IT staff prevent client devices (endpoints) that don’t adhere to company security policies from getting on the corporate network and causing damage, whether malicious or unintentional.

According to Mark Griffiths, Vice President of Authentication Services at VeriSign, the two companies are working right now on a white paper covering this, which they hope to publish “in the not to distant future.”

UA from VeriSign uses multi-factor authentication such as USB keys or smart cards, even one-time use passwords, to confirm the identity of a user. This would not necessarily be required in the architecture the company is working on with Microsoft, however. UA will provide a certificate of health to an endpoint, which would be compared each time the computer logs into the NAP network. If anything has changed, users could be locked out or advised to make changes that once again meet the corporate policy. UA will integrate with Microsoft’s authentication servers and Active Directory.

Companies in the Wi-Fi space like Bluesocket are already working with NAP to try and protect client devices.

Last year, VeriSign started the Open Authentication Reference Architecture (OATH), through which it hopes to push authentication standards for use on all networks, wired and wireless, from the corporation to the ISP.

Upgraded Wi-Fi Security for Windows XP SP2

Filed under: News & Events — evilbunny @ 9:00 am

Microsoft officially announced the availability of a free software update that adds Wi-Fi Protected Access 2 (WPA2) protections and Wireless Provisioning Services Information Element (WPS IE) support to Windows XP SP2. The software giant hopes that the software, which was quietly released in April, will help spur the adoption of wireless access among enterprises and government agencies that have been leery of letting their data take to the airwaves.

The software’s WPA2 certification affirms that the OS conforms to the Wi-Fi Alliance’s 802.11i standard, which boosts the security of wireless networks and can help wireless internet service providers (WISPs) streamline their network deployments.

WhereNet Tracks What the Army Assembles

Filed under: News & Events — evilbunny @ 9:04 am

When parts are missing in action at the U.S. Army’s Tobyhanna assembly depot—a facility the size of 35 football fields— it causes operation glitches and costs a lot of money. That’s why WhereNet’s wireless, real-time parts tracking technology is being deployed by the military (as well as car makers, high-volume seaports and other industrial enterprises) to quickly locate inventory and manage assembly in vast work spaces.

WhereNet, based in Santa-Clara, Calif. and employing 80 people, sells systems that use radio frequency identification (RFID) tags, wireless networks, sensors, telemetry and software to show where components are as they make their way through the manufacturing process. It’s also used to track containers and trucks in shipping and receiving environments. As a result, companies can cut labor costs associated with manually finding lost items. Inventory can be managed more effectively since workers can see exactly what’s on hand, avoiding duplicate orders of missing parts, and the whole operation can be done in less time for less money since bottlenecks can be prevented.
