... Dr Joanna Morgan, of Imperial College, London, UK, told BBC News Online: "An impact the size of Chicxulub occurs on Earth about every 100m years.
"That two such impacts occurred within 300,000 years and both hit the Earth at almost exactly the same place is statistically unlikely."
I think there are numerous explanations of why asteroids might hit earth in "clumps".
After all when Comet P/Shoemaker-Levy 9 impacted Jupiter, it hit
as at least 21 discernable fragments. If some of them had missed the first time, they would probably have hit some time later, being on intersecting orbits and all.
This is why you should always get your cash at the
grocery store -- you get cash that someone else
just used to pay their grocery bill, and when you
spend it somewhere else, it looks like they
spent it -- to someone tracking serial numbers
at the bank.
Of course, to get cash at the grocery you have to
pay with your bank card, so that A.C.Nielsen knows what groceries you buy...
Back when I used to get lab equipment:-); it was
usually from
Purdue University Surplus & Salvage
which used to always have various and sundry interesting stuff.
Actually, its the ones who think that they know what's wrong who are the most difficult to help. They tell you all the information that led them to their conclusion, ignoring the one fact right in front of their nose which would contradict it...
You can do multiple-port and/or multiple IP based virtual hosts just fine with one apache instance and virtual servers. We're doing about 70 at my site.
The only really ugly case is trying to do named virtual host SSL; which would work fine if you could get the browsers to agree on how they verify certificates:
For IE, put multiple CN entries in your certificate.
For older Netscapes, make the *first* CN
be a wildcard matching the respective hosts
For newer Netscape/Mozilla builds, who knows?
But if you're already running the SSL servers under apache, you just move those vhosts into your other configuration and just run one server.
You may have to specify the SSL options in each <VirtualHost> section, rather than configuration -wide though.
You just have fewer total httpd's running, and that will be less overhead.
I agree that the combination-degree gives you the potential to do something really great.
However as to the mechanics, in most major metropolitan areas there are at least 3 universities offering MS in Computer Science as an evening course set, and possibly MS in Electrical Engineering.
I'd recommend an MS/CS and a few random EE courses (esp. digital logic design, maybe something on robotics/control theory), so you've got some familiarity with the physical hardware aspects of
Computers.
Having survived medical school, keeping up with the average MS/CS crowd shouldn't be too bad,
especially if you learn a little programming on your own first, and brush up on set theory/discrete math a bit first.
Hmm... while you get "Ook! can't link to bugzilla form slashdot" if you try to follow the link;-),
If you cut/paste the link (shades of the initial subject!) you get a bug that's RESOLVED, about replacing some of the XUL code. (Apparently there are some serious "Ghostbusters: Gatekeeper/Keymaster/Xul fans in Mozilla-land...)
Perhaps that link doesn't go where you thought it did?
Rather than stop it let's get in on the ground floor -- we'll start a company, (or better yet buy up an existing one that's going out of business) build a big database of names, snail-mail addresses, e-mail addresses, and telephone numbers; copyright the database and then we can sue all kinds of folks:
Phone companies
Online businesses
spammers
The IRS
for having illegally copied versions and/or deriviative works of our database.
We'll sell lots of stock at inflated prices, then sell it all just before we lose the court cases.
It depends more on how many instances of code copying they're alleging: If there are three instances involving 1000 lines of code each, (for example) you only have to write up the interrogatories for the three instances, and say what lines of code were involved in each one.
I think the realy problem they're going to have, though, is that I suspect they don't have access to the AT&T authors of the SysV code to find out where it came from. We'll have Linux authors saying when and where they wrote the code, and all SCO will be able to say is they got it on tape from Novell via AT&T. No information about how the code was created, or when, etc.
But you have to remember that with scientists, likely is a much stronger statement than you seem to think -- i.e. more than 80% probability.
Phrases like watered-down are an inaccurate characterization of the statement.
The fact that they published it at all means it's the strong majority position of the Academy. I can try to find you a reference for that if you want.
You are quite correct that the Kyoto doesn't do nearly enough to solve the problem, assuming it exists. The Real Environmentalists I know consider it a first step, in vaguely the right direction, at best.
And of course, there are non-human sources of CO2; the problem is if those are increasing also, we would need to back our production off even more to maintain the status quo of
C02 atmospheric levels.
Um... did you read the link?
Particularly the part that said:
4. The results of FSIN for inputs near PI and FCOS for inputs near PI/2 deviate greatly from the precision indicated in their documentation. This appears to be a problem that is not widely known and the rest of the discussion here deals with this problem.
The reason folks say that the majority of scientists agree is that the
National Academy of Sciences
has issued
reports
on the topic, which are the result of review and agreement of their
membership.
Even more interesting, to me, is that when the National Research Council, at the request of president Bush, included major global warming skeptics on the council, upon reviewing the
body of evidence, they changed their minds about it (see the last two paragraphs of the link).
These are the top guys in their fields, and they make good statements based on real evidence, as opposed to the average/. posting:-)
Probably the Microsoft languages use the Intel trig instructions.
In the case of Java, you find that the Intel floating point trig instructions don't meet the Java machine spec. So they had to implement them as a function.
The sad thing is, no. Nobody knows the PFA for fingerprinting in general, much less this
specific biometric gadget. It's the dirty secret of law enforcement, but noone has ever scientifically established the "fact" that all fingerprints are unique; few if any studies about how common various features of fingerprints are have been done.
And at 60 billion fingers in the world (ten per person remember), you need some really large probabilities in fingerprint formation to reasonably rule out duplicates...
It's more obvious if you scale it up to more CPU's.
It actually makes more sense to build one chip that's, say, 8 logical processors and give it several execution units of each type (i.e. 6 integer math units, 4 floating point units, etc.) depending on instruction mix. Of course, that eats chip real estate, but if you have a multithreaded system to run, it will scream.
If you put in 8 distinct processors, that's 8 integer math units, 8 floating point math units, etc. some percentage of which are idle most of the time. So arguably some of those math units are just plain waste -- I mean if your floating point unit is idle half the time, you could get by with
half the floating point units, and just schedule the threads on the right CPU's, right?
With 2 logical processors, its more of a percentage thing, and harder to see.
I'll be impressed when they add, say, enough extra processing units that it actually performs more like a dual CPU (if you give it enough cache, anyway).
progressively back off 1cup/day per week of coffee 'till you're down to one or two cups a day.
take a 4 day weekend, take antihistamines (i.e. Benadryl, Clortrimeton) to help you sleep all weekend, and take ibuprofen for the headaches.
If you sleep for most of three days, I've found you can happily go without caffeine indefinitely, at least 'till the next time you want to stay up all night:-).

Is it even 50%? I thought it was 50% of registered voters, but the registered voters number was less than 50% of those eligable...

- buy companies that have the patent, or
- armtwist them into cross-patent license agreements.
Both are much quicker than actually fighting a patent lawsuit.They even take requests
Of course, if you're not near Northwest Indiana, it's probably not all that convenient.
If you're near Chicago you can always check out American Science & Surplus, or you can order stuff delivered from their web site.
Gee... sounds like an 8-track tape to me :-)

It all depends if you want accuracy or speed.
We already did vote Bush out, last time I checked, but somehow he finagled his way into the White House anyway. :)

Now if the FBI had found the threat email without the company telling them about it, that would be Carnivore :-).
I don't recall that Einstein was terribly rich, for example, but most folks agree he was pretty smart...
- count runs of punctuation as tokens
- run a normal pass, then
- de-html-tag the text
- map "w,.o..r!#d_=s" into "words" (de-punctuate)
- run a second pass
- use individual words *and* pairs of adjacent words in the statistics database
Then we'll get even better filtering, and foil about 90% of the current techniques.Of course, then the spammers will start poking around for new techniques... But these are really easy to fix.
