If the database fits into that amount of RAM, then wouldn't that mean I/O is not a limiting factor?

Depends on whether you still need the database around if the power ever goes off.

In some applications the DBs are just read-only or temporary and you copy/build them from permanent storage so it doesn't matter.

But in many other DB applications you do need to write and it needs to actually be permanently written (within monetary and physical constraints). And it often has to be written when you tell the user it's written. Bad stuff happens if you tell the users/customers "transaction succeeded", delay writing the transactions till later but then the power/battery fails and there's completely no record for thousands of transactions.

Submission + - How Not to Design a UI: Slashdot Beta Site is a Train Wreck (slashdot.org) 1

iggymanz writes: As with Canonical's Unity and Windows 8, the majority of otherwise intelligent coders are completely out of their element when trying to make a user interface. They fly off on tangents, ignoring any user needs or input, making something understood and useable only to themselves. A bad UI is neither discoverable, learnable, efficient of space, nor capable of providing proper feedback to the user. With apologies, I link to the vilest and most aweful forum interface misdesigned by the minds of idiot-savants in full idiot mode, the Slashdot Beta Site.

As Ars explained, "RSA's defense seems to be that officials didn't know the NSA-influenced deterministic random bit generator had weaknesses that could be exploited to crack adversaries' cryptographic keys."

Whether bribery was involved or not, RSA used an algorithm without validating the math.

Not everybody feels that a currency backed by violence is an ethical arrangement.

Of course it's not. The question comes down to this: what's the alternative? So far, nobody has come up with a method to protect physical assets that doesn't involve physical security. Bitcoin doesn't solve this (nor does it attempt to.)

Nor do they feel that allowing politicians to destroy the value of a currency is a wise course of action.

How is letting a group of bitcoin power users alter the currency's value any different?

First of all, there is only one issuer of bitcoin: the bitcoin network, acting in aggregate, according to a pre-agreed algorithm.

Which is to say, the number of bitcoin can be changed as long as a sufficient number of people agree to change the algorithm.

Secondly, the value of almost any modern day currency is entirely a perceptual value caused by the notion that people will accept that currency at some approximately-known rate for payment for goods or services.

In theory, sure. In reality, there's a reason that countries with strong currencies have strong militaries to protect those currencies.
