Because the reality of climate change is that the rich will be able to adapt to moderate climate change (unless your assets are mainly in coastal property). The poor however and that includes the poor in the US will not. A great example of this is New Orleans. What was striking was that the faces of the people stranded there were mainly black and that they were mainly from poor neighborhoods. They all heard the calls to leave the City but lacking access to transportation and lacking a place to go outside the City they chose to stay put. The middle class all had access to good transportation and had no concerns about finding somewhere to stay when they left the city and so they got out while the going was good. This is pretty much what will happen with moderate climate change from The Sudan to the Louisiana Delta. This is why the leaders of all the major Christian churches in the US and worldwide have stated that it is your moral duty to try to avert climate change. regards Andrew Harrison ------------------------------ Date: Mon, 16 Apr 2007 02:15:00 -0400 From: Bill Todd Subject: Re: OT: OpenVMS Message-ID: Richard Maher wrote: ... > Regardless of the state of decay of the corpse COV, I submit that the acts > that you (and more notably others) are performing on it are unseamly at best > and, hopefully, illegal in most of your states! 'Unseemly' really doesn't bother me excessively unless that's my own opinion (which it clearly is not). I don't know about 'unseamly', though: some of the more interesting parts of life are found around seams rather than well within the boundaries of a homogeneous field, so on balance I think I'd probably be for it. As for legality, the PC police have not (yet) become quite that influential, and I sincerely hope they never do - especially as those holding different views have several very effective personal options which they can exercise unilaterally if they don't care for certain topics here. You note that you yourself have by virtue of responding contributed to what you apparently consider to be an inappropriate noise level here, but rather I'd ask why you were still reading this thread at all - since by simply ignoring it you would not only have reduced that noise level but also would have remained blissfully unaffected by most of it. "Live and let live" really does have a great deal to recommend it, unless a) the actions of others have significant and unavoidable effects on you or b) you're really into telling other people how you think *they* should act (see reference to the PC police above). I myself wish that this forum were as technically interesting as it used to be, but comatose OSs just don't tend to generate the kind of vigorous technical discussions that more vibrant ones do - which leaves many members of their communities (at least the ones with something better to do than just sit around) with the choice of moving on elsewhere or finding other topics of interest where they still are so that just in case something of technical interest *does* come up they'll be around to catch it (though one would have to be even more of an optimist than I am to think that's very likely after so many years of ever-increasing doldrums). In any event (as I've suggested before) you probably will have much better luck taking personal steps to increase the number of posts that you consider on-topic than in attempting to suppress the number of posts that you consider off-topic: this particular community of cats does not seem very receptive to being herded, but might respond quite positively to being inspired. - bill ------------------------------ Date: Mon, 16 Apr 2007 07:35:34 -0500 From: bradhamilton@comcast.net (Brad Hamilton) Subject: Re: OT: OpenVMS Message-ID: In article , Richard Maher wrote: >Hi Brian, > >> BTW, I will have a friend from Denmark (Horsens) here for a week beginning >> late next Monday.

One thing we do know is that each Rock thread has at least one scout thread which runs ahead of the hardware thread in essence warming up the cache for the thread itself. Scout threads are an interesting way of solving the prediction problem but how many there are in each Rock core is open to conjecture at this point. It will be interesting if they only do an 8 module system, the implication being that Sun expect that 8 rock modules will provide enough throughput to cover the entirety of the current Sun range with increases in throughput beyond what the 144 core F25K can support today. > ### > > Like it or not, this is another proof of why it was dumb to kill Alpha and > then defer that problem to Intel ("hey, we want to be more like Dell").

I am not sure you can read this into Sun's Rock announcements. If Rock proves to be the way to go it will also prove to be a fundamental shift in the way people develop cores. This would have been just a big a shock to an Alpha platform based on what Compaq were proposing with EV8 as it may prove to be to vendors developing servers based on Itanium. EV8 would have been big very complex and relatively power hungry. Complexity and power have been the driving forces that have propelled the aggressive multi-core developments and HP would have had to dramatically re-jig Alpha development as Intel and Sun have done to keep Alpha competitive. IBM's issues getting the Power 6 out may if the rumors are true serve to illustrate the issues which could have afflicted Alpha. But we will have to wait and see if Rock works, Scout threads, Out Of Order Retirement etc are all novel technologies and we will only know if they work when people start getting their hands on Rock based systems.
