>>>>It's not something I am going to get worked up over. Not only is the power back on after being out most of the past four days -- always fun in mid July -- I found a job. What a relief. VFP, SQL Server, C#.NET. Beautiful.

>>>Why no power ? Was it a widespread outage (horrible american word :-} )
>>>Congratulations on the job (No WPF though :-{) Will it entail much travelling (or even relocation) ?

>>>One of the companies I work for is currently beginning the process of looking for an additional developer working primarily with WPF - it will be interesting to see the type of applicant we get......

>>I was out of town when it happened so didn't experience it directly. In fact I was almost all the way back home before I knew anything happened. 75 mph winds swept through Chicago at around 8 Monday morning, The electric company said 865,000 customers were without power, a record. The physical damage was not that great, just lost power and a lot of dead trees. Everywhere around here downed trees and branches are stacked by the side of the road. No loss of life, so we were a lot luckier than the the tornado and earthquake zones. Nobody died. It was actually somewhat interesting living unelectronically for a few days. When the sun went down that was it, that was the end of the day. No wonder everyone had 10 kids back then.

>>Will give you details about the job privately. After the past several months I am a little paranoid.

>Last time we had a power cut I thought no problem I'll get the camping gear out and cook on that . then found it was in the garage which had a power door. But I did then find that using a trivet and a bunch of tea lights you can boil a pan of water for tea or to cook. You get a surprising amount of heat with 10 or 12 tea lights.

Reminds me of the Welsh comedian (whose name I can't remember) being cracked up at the thought of buying a 'million candle power' flashlight. Envisions going down the cellar with a candelabra and shouting back to ask his wife to bring down another couple of thousand candles because he couldn't see well enough ....
