• Connecting a building to the campus LAN

  One reader asks: "I have been asked to connect a building to our network that isn't currently connected. While this building, albeit a small one, is a stone's throw from two other buildings, the decision was made when the fiber backbone was installed between the building to not include this building because it was due to be torn down in the near future. That was several years ago and before my time but the building still exists. I have now been asked by a department head to provide costs estimates for connecting connecting the building to the network. After consulting the drawings for the fiber backbone, there is conduit running to the building but only phone lines were run to the building. Only a couple of people are expected to be in this building at any given time. What will be the best option for connecting this building to the network?"

• Use less paper, save money

  A few years ago, there was lots of excited chatter about how we were on the brink of becoming a paperless society. No longer would offices be cluttered up by reams of reports. Faxes would be replaced by electronic communiques. Even items that it seemed would have to be printed because they required a physical signature would disappear as we learned to trust digital signatures on e-mails.

However, a way of physically connecting devices using something called Powerline -- a concept that has been around for three or four years -- is now making its presence felt in the U.K.

• Kernel space: Buried in warnings

  The 2.6.19-rc4 prepatch release did not go quite as well as the developers might have liked; some confusion over the return type for an internal function led to an undesirable mixing of pointer and integer types in the depths of the block layer. As it turns out, gcc noticed this problem and duly issued warnings about it, but nobody saw them before the mistaken patch was merged and the resulting kernel shipped. This is, in other words, a problem which should have been easily avoidable.

• Preparing for disasters

  Thinking about disaster recovery, a year after Hurricane Katrina, and on the fifth anniversary of 9/11, it's a good idea to look at contingency planning, especially for the organizations that would need to operate during a disaster. This is a different issue than transferring operations to a remote site. There are various issues in operating in a disaster environment, usually starting with electrical power but also extending to employee concerns and the need for resupply.
