I am not doubting that these new gases will allow you to survive but I've been too close for comfort to a fire in a Chemistry lab and without adequate training (not in the use of a fire-extinguisher but in the behaviour in case of fire) the last thing I did was "stay calm"... I just hope that places which install this system give adequate training to their people as to what can be done.
Even the obvious like "lie low as smoke rises and there is more oxygen at ground level" and to "try and cover your mouth & nose". At least, this is what I learned from that incident, sadly after the fact.
Compaq Armada E500s are now no longer in production but the ten we bought both as a company and as individuals all came with 12Gb Fujitsu 2.5" hard-disks and each one of them has failed and had to be exchanged. While under warranty we had them exchanged with other Fujitsu drives all of which subsequently failed. They were replaced in-house with IBM TravelStar 20 & 30Gb models which have performed flawlessly ever since.
Our original suspicion was the usual "bad batch" but since we bought the E500s two at a time that was somewhat unlikely. When the drives coming back from "maintenance" failed too we definitely decided it was a Fujitsu issue and not a "bad batch" issue.
Simple: it is a seismic area (terrible earthquake in Messina in 1901 inclusive of tsunami) with the fault ine running right between Sicily and the mainland. The currents are particularly strong which make a "suspended tunnel" (one of the original designs) also impossible. Apparently the only design with a sporting chance to work is a suspension bridge.
Intel: Buys its way out of a lawsuit for stealing 64bit microcode from the DEC Alpha, then buy's the Alpha from Compaq to discontinue it. Then create a brand new 64 bit chip using their own limited talent, while shoving the existing 64 bit platfrom into an early grave.
The above is an incorrect statement: the first lawsuit between Intel and Digital was over the Pentium Pro and the breach of a number of VAX CPU (CISC) patents, if I remember correctly in the specific area of cache management (possibly because the Pentium Pro CPU was the first to have an on-die L2 cache).
The lawsuit was settled with Intel agreeing to buy Digital's networking group (ie. the chaps who built hubs and the like) and an old fab which was manufacturing Alphas but would soon be out of date.
What happened recently is that Compaq (which in th e meantime purchased Digital and Tandem) sold off the Alpha to Intel. There are a number of rumours regarding this sale, mainly in the field of Intel purchasing Alpha to make Itanium work - allegedly Itanium II is going to "include" a number of Alpha technologies. At least this is what I've been told at a number of Compaq "technical briefs" (aka PR events or free lunches).
To be precise when Digital came out with Alphas which could run NT the first model was the PWS (Personal Workstation) 500a. It featured the EV56 version of the Alpha chip which included byte-manipulation instructions to speed up stuff under FX!32 and generally to make the NT port simpler.
One of the key features of the PWS was that it had a "dual mode" BIOS, one was the SRM console which all old Digital OSF/1 hands will immediately recognise as the ">>>" prompt and the other was the AlphaBIOS which provided emulation of a PC BIOS services for the NT side. The 500a model only shipped with AlphaBIOS, the 500au shipped with SRM.
"Where can I find SRM?" is a frequent request on the tru64-unix-managers mailing lists, you might want to search the archives
to check if you can simply download and upgrade the firmware (it is freely available from the Compaq support web site). I seem to recall that this was not possible because the AlphaBIOS won't let you do it.

Intel stole and then implemented Alpha technologies for its Pentium, and only much later did it negotiate with Digital to get the official right to use that stuff.
Nope, this one is definitely a bad line. The story goes back into the midst of time but what actually happened is rather confusing: at some point Digital sued Intel for patent infringement and everyone started shouting "Pentium copies Alpha". The apparent truth as told by a Digital chap to me at the time is that the VAX CPU cache design was copied in the Pentium Pro.
Digital sued and the settlement was that Digital sold its networking division to Intel for an undisclosed but not trivial sum and an oldish fab (with outdated lithography equipment) and they left it at that (including the fact that the PPro line was EOL'd). This is why the old DEC Tulip network cards started appearing as Intel parts.
The above is certainly a very good point - not only, in the UK you can go with the logs to the PostOffice and have them cover it with a pretty date stamp - the same they use for annulling stamps. The moment they have done that you have created a "before" and "after" in the logs, and it becomes rather hard to forge anything which is covered by the stamp's ink. Also, sign the logs at the Post Office (witness) and make sure that one of the stamps covers your signature.
Granted, nothing is perfect but the whole point is to raise the bar so that it withstands serious cross-examination.
At the end of the day can you prove that the packets which came into your external interface were not fabricated (ie. the whole attack is a complete fake)?
One of the things that always puzzled me about this approach is the need to re-calculate the metrics almost with every hit. There was a period of time early last year when the security mailing lists were full of people complaining about F5's product effectively acting like a scanner.
My view on this is that once you've calculated a metric there is really no need to go an recalculate it so often, after all the changes in topology are not that frequent, in particular for non-US sites (fundamentally you are at the end of a pipe, often congested, to the USofA). I wonder how much congestion their high-priority ICMP traffic provoked...
Funnily enough the italian daily newspaper, Corriere della Sera had a lengthy article on Giordano Bruno on Wednesday 16th. Unfortunately they don't believe in archiving previous pages on their web site (since they sell their archives CD for a hefty fee). I will try to summarise it from what I recall. The author is the organiser of the conference which is taking place in Rome (Italy) sometime next week. He is trying to bring out the "forgotten" side of Giordano Bruno, namely his scientific views which, according to the author, had been pillaged heavily by the likes of Galileo. In particular he states that Bruno had developed a theory of the universe in which not only the Earth orbited the Sun (i.e. heliocentric and against what was the scholastic view of the time) but that the Sun itself was not the centre of the universe. Furthermore Bruno believed that stars were nothing other than other "suns" which had other Earths orbiting them (another pretty heretical statement at the time).
The article which is partially in the form of an interview then delves in the various historical descriptions on the burning on the stake and the horrendous tortures at the hands of the inquisition and closes inviting people to the conference.
P. Ribenboim, "13 Lectures on Fermat's Last Theorem", Springer-Verlag, 1979, ISBN 3-540-90432-8 (assumes undergraduate maths). You might notice that this book's publication date is way before Wiles, it contains material on which Wiles then expands, e.g. elliptic curves (cf. cryptography too!) and modular forms. A simpler text, still by Ribenboim is "Fermat's Last Theorem for Amateurs", 1999, Springer again, ISBN 0-387-98508-5, which, as the title sort of implies is a tad easier. I wouldn't say it is exactly trivial but it is a very good self-contained book with a number of chapters explaining the number theory you need and a good attempt at explaning Wiles' proof. Borrow this one from your local library if you are really interested and have some mathematical background, the first one if you are into higher mathematics.
