Comment Re:distribution of primes (Score 1) 509

primes are beleived to be distributed as

#primes x ~ x/ln(x)

No longer. It is a full-blown theorem and it is a fact that the number of primes under x asymptotically approaches x/ln(x) as x approaches infinity (this is interesting as changing the ln() to a log() in any other base fails).

as can be seen the number is more linear than logarithmic.

There is some term describing O(x/ln(x)), I'm sure. But I wouldn't call it any more linear than it is logarithmic.

Data Storage

Encrypted But Searchable Online Storage? 266

An anonymous reader asks "Is there a solution for online storage of encrypted data providing encrypted search and similar functions over the encrypted data? Is there an API/software/solution or even some online storage company providing this? I don't like Google understanding all my unencrypted data, but I like that Google can search them when they are unencrypted. So I would like to have both: the online storage provider does not understand my data, but he can still help me with searching in them, and doing other useful stuff. I mean: I send to the remote server encrypted data and later an encrypted query (the server cannot decipher them), and the server sends me back a chunk of my encrypted data stored there — the result of my encrypted query. Or I ask for the directory structure of my encrypted data (somehow stored in my data too — like in a tar archive), and the server sends it back, without knowing that this encrypted chunk is the directory structure. I googled for this and found some papers, however no software and no online service providing this yet." Can anyone point to an available implementation?

The way Conway and Kochen have defined "free will" is, loosely, any behavior that isn't determined by the past.

Then humans don't have free will. There is no human behavior that is independent of the past.

This is a definition seems unfit. In fact, according to this definition, nothing has free will, as everything is determined by its past.

That's why humans make terrible random number generators. All of our number choices are strongly correlated.

Wow, way off. Mod parent down.

Speakers are themselves fundamentally flawed. Headphones can send sound to the exact location needed while speakers are "ballparking" where the listener will be.

Space limitations are null, audio positioning is null, and annoying your neighbors is null.

Furthermore, good headphones have the capacity to send much less-distorted, higher-quality sound than speakers.

Good headphones will always produce better sound than good speakers. If you don't believe me, ask your local audiophile/audio professional. I guarantee you, if he takes himself seriously, he'll agree.

IANAL, but the way I understand it, monopolies in a specific market within the United States are OK as long as they don't try to leverage another market.

How is this different from Microsoft's monopoly? Microsoft tried to use Windows (where it had a virtual monopoly at the time) to make everyone use Internet Explorer. They were largely successful but they were also sued.

The way I see it, Apple is trying to use Shuffle, which has a virtual monopoly in the tiny screen-less talking music player department to leverage, to Apple's favor, the headphone market.

But it's alright because I'm not getting a shuffle anyways.

I'm sure it's pretty profitable, in some way, to infect web hosts and the like. A majority of web hosts run Linux. Therefore Linux is already a target. A pretty big one, if you ask me.

So please explain to me why they're going to target desktops instead of servers.

Yes, a dumb user is a dumb user, but you must agree: it's much harder to mess up riding a tricycle than a bicycle. They're both vulnerable to flipping over but it happens that tricycles have safety measures built-in to prevent many things from happening while riding.
