    It's the information. Have you actually listened to some of the things that they're demanding you not use? The last few lists I have heard rattled off before takeoff have included GPS devices. What? GPS devices are passive, they are receive-only. So what does the airline care if I have one connected during the flight?
    First of all, all radio receivers built since about 1920 also act as transmitters, so even a passive GPS receiver has the potential to cause interference.

    Second, use of GPS devices in flight is at the discretion of the airline and the captain of the airliner. Most US airlines either do not prohibit, or specifically do allow, use of GPS receivers during flight (not during takeoff and landing). If you have any question or concern about that, the First Officer or Captain is usually standing by the cockpit door during boarding and you can ask her if it is OK to use the GPS.

    And finally, while airlines do some things to maximize revenue, they also do a lot of things strictly in the name of safety. Since the exact effects of RF interference from consumer electronics are not known, some airlines play it safer-than-safe and do not allow them in flight. That is their call and quite sensible.

    Over a week ago, Asa pointed out that the Firebird name might not stick for more than a few months [mozillazine.org]. In that post, he mentions Mozilla Browser as a possible name for the 1.5 release.
    That stance, though , is a bit inconsistent with other statements that "Firebird" was approved all the way up through the AOLTW chain of command. One would not spend the political capital to get something like that approved by the "corner suits" if it were intended only for internal consumption.

    Then you're probably out of business anyway, so what does it matter at that point?
    I'll reply to this message, but cover several similar points.

    First, I should note that I do consider sanity checks and cost/benefit analysis when making backup/recovery plans. So I agree with many of these comments. BUT...

    (1) Disasters happen more often than people expect. And they can happen to you, not just the other guy. Wildpackets almost went out of business as a result of underestimating that.

    (2) Being out of business anyway - well - that's a discussion I had with the owner of one small company. I pointed out to him that one of his core values was loyalty to his employees. In the event of a big disaster, he and his family would collect the insurance check and sell the site, but his (former) employees' mortgage payments would continue. He got the point and agreed to improve disaster recovery plans.

    (3) "Both of our sites will never get hit at the same time". I had a friend in charge of DR for a large company who analyzed 10 years of data center disasters and came to the same conclusion. He put the backup right down the street from the primary. Ever hear of the Great Chicago Flood? Luckily for my friend he was working at another company when both his primary and backup were taken out by that event!

    That's my 0.02 anyway.

    There's one aspect in which Dr. Koch's backup system can't keep up with tape solutions: storing the backup medium in another location after the backup has been completed.

    As long as this isn't necessary, Dr. Koch's backup system offers some rather unique advantages.

    Out of curiosity, what is the use of a backup that is not periodically rotated off-site? And by "off-site" I mean at least 50 km away? What happens when a tornado takes out the building holding the critical data AND the building holding that nice array of IDE drives 2 minutes apart?

    Compared to many other projects, designing and implementing a secure, accurate voting machine isn't technically challenging. The challenge comes in proving that the voting machine is both secure and accurate.

    The fundamental problem being that the people who write the specs, make the purchase, and oversee the proof testing are the same people who have the greatest conflict of interest in the entire process. I am not saying that all politicians would cheat if they could, but by their vary nature successful politicians are people who are driven to be elected at any cost.

    This comment has been made every time a new processor comes out, and the usual reply is that there are plenty of applications that still require more CPU performance (which there certainly are), and sooner or later there will be one which is sufficiently compelling that Joe Sixpack will upgrade
    However, what really happens is that the major box manufacturers need to keep their price points between $1500 and $2500 - if the prices for the "basic machine" (as actually sold - not as advertised in the Sunday paper) fell below that they would not be able to survive.

    So Dell, Gateway, HP, etc. work with Intel to assure a constant flow of "new, improved, and faster" CPUs, put those in their boxes, and terminate the "older, slower" systems. Then the volumes on the slower chips and their associate motherboards fall and Intel terminates them due to "lack of demand". So the cycle continues.

    Other than gamers and a few applications heavily dependent on processing (when was the last time you folded a protein) very few PC users have gained from the speed increases of the last two years.

Hell, my next-door neighbor died in a traffic accident caused by pure stupidity on the other driver's part yesterday.

    I have lived in several North American houses >100 years old, and I was sure that most of them would last another 100 with proper maintenance. So it is possible.

    However, a problem you will face is climate control and ventilation. Those 1800s houses were drafty, had huge non-living-space attics, and had poor energy efficiency. After thinking about it for a while, and visiting friends' tract mansions that smell of mold and rot 18 months after completion, I am convinced that the excess (and energy-consuming) ventilation through those old houses is a bit part of why they last so long.

    Unfortunatley it is no longer acceptable to have your bedroom go to 110 deg.F in the summer and 38 deg.F + draft in the winter! So were I designing a new house to last, I would add a very large heat exchanger and the necessary vents, fans, smoke detectors, dampers, etc. to force-draft a good amount of air through the house. This would probably mean a duct system separate from the air conditioner (I would probably use radiant floor heating). And also a lot of motors, fans, controls, etc - so buy spare parts for 20 years down the road.

    Your idea of an insulated equipment space between the top floor and attic is a good one - possibly you would want to put the heat exchanger there. And I would go ahead and wire for Cat6 and CATV, since technologies like that don't go away as fast as people think. But use conduit so you can change your mind on the media later.

    Other things I would consider: real plaster and lath walls, copper supply / cast iron waste pipe, and for sure lots of access hatches so that things can be fixed without disassembling the walls.
