Illegal but fun broadband access

slurpr

The Slurpr, a WiFi access point which aggregates up to six ‘available’ (actually, unprotected) 54 Mbps WiFi channels into (as the link puts it) “one bigazz, ‘free’ connection”. It is the latest invention of Dutch hacker, Mark Hoekstra and his friend, Boris Veldhuizen van Zanten. Of course, use of the Slurpr in its current incarnation will likely violate wardriving (warbiking in the Netherlands) laws in certain countries. One can bravely pre-order Slurpr at Mark’s site for EUR 999 (US$1,347) a box today.

The 1,400 or so residents of the wee village of Knegsel in the province of Noord-Brabant are the first in the Netherlands to get to use a new wireless Internet service via Wimax. Internet company Casema expects much from the possible successor of UMTS. It is 13 times as fast and is perfect for areas where residents are spread thin. In and around Knegsel there are three antennas, which provide wireless broadband Internet over distances of up to 25 kilometres.

Stop hackers

Automate your network intrusion detection; that seems to be the inevitable conclusion from Sebastiaan Tesink’s research into systems that can teach themselves to recognise hacking attempts. Tesink performed his research as part of his Master’s thesis. According to his conclusions, automated systems can learn to recognize well over 90% of all hacking attempts, helping system administrators considerably.

Tax day = Open Source day

Filed under: IT by Branko Collin @ 9:34 pm

Today is tax day in the Netherlands: time to get these return forms in and hope for a bit of cash from the government. Two years ago the state started demanding that business owners start filing their reports electronically, using a Windows and Mac only tool based on Adobe’s PDF. Last year they got smarter and developed their own tool, which works on Windows, Mac and GNU/Linux. The secret ingredient? Open Source libraries. Specifically: gSOAP, OpenSSL, wxWidgets, GTK+, ZLIB, Independent JPEG Group components, Autopackage, and NSIS.

Computers learn to talk to each other

Filed under: IT by Branko Collin @ 8:25 am

When a PC talks to a printer, the PC has to know in advance how to address the printer and what the printer is saying.

On March 21, PhD student Jurriaan van Diggelen will defend a thesis that suggests a system where ‘agents’ (autonomous computer programs that act on behalf of a user) learn to communicate with other agents on their own. Such self-learning software could for instance be used to search the Internet for cheap holiday packages, collecting the necessary information from the servers of travel agents, airlines, hotels and so on, even though the program would initially not know how to talk to these servers.

The thesis is called Achieving Semantic Interoperability in Multi-Agent Systems (PDF). Via Web Wereld.

Van Diggelen tested his theories with a sophisticated RSS agregator. He identifies a translation problem: different systems know about the same concepts, but give them different names. The agent has to learn the names that apply to the same concept. A second problem is one of specialisation: “So you don’t know about ‘football’, but do you know about ‘sports’?”. The aggregator could reply “Yes,” and provide a more generic answer than it was looking for, but still one that could be presented to the user.
