It's not just the Taliban that's scared of mobile phones now

Written by David Noel-Davies
Monday, 28 April 2008
If you are, the chances are that your concerns have focused more on their ability to act as cameras and portable memory devices - unless of course you're the Afghan Taliban, and you think the infidels are targeting your cellphones for missile strikes. Now though, the western worshippers of the Great God Security, in whose mighty name all things become possible - no matter how absurd they may be - want to worry us about the cellular side of things as well.

Connecting two buildings to one broadband service

Written by David Noel-Davies
Sunday, 13 April 2008
Problem: - I need to connect two buildings which are 100 metres apart. Both buildings are using wireless networks and one has an ADSL modem. I want to ensure both buildings can access the LAN to use shared resources and the Internet through the single ADSL connection. Solution: - Before getting started, look at the total number of users you will have on one connection and compare that against the speed of your DSL. Depending on your level of service, you may want to increase the speed if you can (this will depend on how far your location is from the central office providing you with DSL). See if you can get broadband service from the cable company. More cable companies are beginning to provide this type of service to companies. You may be able to get better Internet performance for the same money or just a little bit more than you are currently paying.
