Apple does this so they don't cannibalize their own sales. What happened to those people that bought the $3500 monitor only to see it drop to $2000 the next day?
The reason why Netscape left my computer was that DNS queries would lock all of netscape functions. I just hated going to a site and waiting for a DNS timeout before I could regain control of the browser.

As someone that tutored college students who were lost in calc, I sympathize with your last statement. But my experience appears to tell me that its not strictly the mathematicians fault but that students are already "ruined" by the time they get to college. The aparent reason would be that math is taught to be all about numbers and getting the right answer. Ugh, to cut a page long rant into the short form, let's just say there need to be more word problems and at the high school level there should be more proofs done in a more prose like fashion.
Let's refine your conjecture to say that every rational number repeats eventually (terminates means repeating zeros). Every decimal place produced is the previous remainder modulo the divisor. Since a rational number has a finite divisor there can only be a finite number of remainders before one will be repeated. For bonus points the reader can explain how many before it repeats and what it has to do with relative primes.
If I've gotten something wrong above, give me a minute to rewrite my axioms.

Paris was quite the center for Mathematics for quite a while.
I'm guessing the spite is from someone not too fond of his calculus class and not merely a thrashing of the French.
If you're going to go after the French I think its best done by pointing out how the Americans did so much better than the defending World Cup champions this last time around.

It makes perfect sense really. When you remember that a derivative of a function gives you a function that produces the slope at a given point.
So, when you take the derivative of the numerator and denominator you are getting the slopes. Then by comparing those two you see if one or the other is increasing without bound (or toward zero) faster than the other.
Try this for a pattern: 0.10203040506070809010011012013...etc. I don't *think* this is rational, but you'd have to admit there is a pattern and that it won't repeat. Further, because of the pattern in this number, it can be calculated what digit is at any position of the number without examining all the previous digits. This will be left as an exercise for the reader.
No it remains to be seen whether this is part of a valid contract or merely a claim made by MS.
MS software does make claims that is appropriate for certain use (says so right on the package). Further, the company says its not only appropriate to use SQL server but better to use it.
GPL makes no such claims.

I've been using torque (from Apache, under the DB project).
One row in the db equates to one object with all the appropriate getters and setters.
I haven't been using Torque for anything too complicated, but it definitely passes the test of making the simple things simple, and area I find Java to be weak in.
For instance: Torque.init("Torque.properties"); Empl oyee emp = new Employee(); e.setName("Dave"); e.save();
That's all there is to creating a row in the db. There are correspondingly simple operations for select, update and delete so long as you are working on one table at a time. Its a bit messier working with joins.
Its also messy and poorly documented when doing work on the select side of the statement. While "select max(emp_id) from employees" is doable, its not as simple as it could be considering how common select max() is.
I've solved the mystery of where clothes go in the dryer. They turn into dust.
This explains several things. Where dust comes from and where clothes go. It also explains that are clothes don't just *seem* to get smaller every year, they actually are.
heh, until you run across some java 1.4 legacy system and can't buy the book in the bookstore. Then you call the publisher and they say its out of print, tough luck. Then you fix it by pirating a copy and get busted by the newly formed Book Publisher's Association of America.
The whole book doesn't have to be up to date to be relevant. The book could be valuable just for a having a few lines you can use but it will only be valuable if you can get it.
Second, I'm assuming that the clustering solution doesn't just suck.
What I'm suggesting is that a clustering solution would improve uptime for Postgres at the marginal cost of another machine. A cost which still wouldn't put it into the same price range as Oracle but (for some) would reduce the risk enough to justify moving to it.
Of course, I'd still like to see things carved into stone.
This is business. Take $10k and see what you can get with Oracle vs free databases.
The proper comparison for the price will be clustered Postgres vs a lone Oracle server (neither with support).
How do they compare at this level?
This clustered solution doesn't have to compare to the best solution ever by anyone. It just has to compare favorably against those products in its price range.
Moving to Postgres from Oracle would be asking someone to accept more risk in return for thousands and thousands of dollars. For some companies that's the difference between being a 3 man shop and a 4 man shop.
The business world existed and got along quite nicely with paper records for quite some time. Paper records got lost all the time and business went along nicely. The same can be said today, if we were to lose 8-24 hours worth of data it would be bad, but not catastrophic. Insurance against such an even would probably cost a hell of a lot less than Oracle licensing.
Not every database needs to be 12TB and accessible by 2 million users 24/7.
The implicit argument for Oracle is that cost is no matter. Well then, I suggest you hire 12 people to each independently carve your data into stone as data loss there would be minimal.
To all those people that are asking how to move data offsite. This is why employers ask puzzle questions...so they can find people that can think through the problem and don't need to be shown how to do every damn thing.
Just because tapes have always been driven to their destination doesn't mean that's the only way data can move.
As others have pointed out, you can build the hard drive backup offsite and move the data there periodically over this new invention, the internet.
