Comment Region locking is socially unacceptable (Score 3, Interesting) 408

Sounds to me like region locking content has become socially unacceptable in this globally connected age. These people are not only paying for the content, they're paying extra on top of it just to get around your arbitrary restrictions.

Maybe it's time for people like her to join us in the 21st century.

1. Three years ago in Brazil you could buy Bitcoins in local online markets using your local account. Several large markets also accepted international wire transfers. Or you could also go to IIRC, and buy in cash from people geographically near you.

2. There were services accepting Bitcoins that sold gift cards for Amazon and other big stores. Don't know if there are such services still. Of course they charged fees.

In any case, Bitcoin serves three main purposes, as I see:

I. dealing in shady business (silk road, etc)
II. trading and speculating
III. keeping a handful of libertarians geeks thinking they're really "sticking it to the man"

I and II are obviously the reasons Bitcoin still exists. III is not enough to keep it rolling.

Learning facts don't make anyone knowledgeable of science. I think what really means is that your regular software writer (and CS bachelor, IMHO) has no contact whatsoever with the scientific method and with how science actually works. That is, they are unaware of how to develop an hypothesis, test it against experiment, place the phenomenon under a broader context, etc.

A really simple test to see if someone has at least a minimum understand of how science works is asking them about what a theory is. I've seem plenty of college educated people think that, say, Theory of Relativity and Theory of Evolution are mere guesses that haven't still been properly verified and one have not only the right, but the moral obligation to chose whether to believe them or not based on their on personal logic. Actually, most people say things like "this and that haven't actually been proved by science", thinking that there are actually "proofs" of anything in science.

I disagree with how they picture Nye's position as a prominent science educator, but his opinion is right on the dime.

Comment Re:Maybe it's because the music industry has adapt (Score 1) 196

I stopped downloading music and picked up a sub to Spotify instead simply because it's more convenient. I share the same music library on my home PC, work PC and smartphone without having to fiddle with anything. When I'm in the car I plug the smartphone into the deck and listen to the playlists that I've downloaded. Even my AV receiver at home can stream from Spotify. It all just works and I'm always stumbling across new music that I end up liking a lot.

I've even set up a few collaborative playlists with friends. When one of us finds something new we add it to the list, then the others can have a listen and add it to their own private playlists if they like it.

Only two things bother me: not everything is available and some things that were available will simply disappear one day. Same old licensing BS that just doesn't work in a digitally connected world.

One thing is clear though. Previously the music industry made no money at all off me, now they do. Not because of some anti-piracy campaign but because someone was finally able to provide an acceptably priced product that's more convenient than pirating. Funny how that works.

That's possible yes. I guess you could already snap a photo of your completed election ballot to show to those thugs, but you're right that it'd be easier for them to verify votes if they can coerce you into giving up your ID.

If you ask me having those kinds of thugs around in the first place is a pretty good sign of a broken system, but it's a fair point anyway.

How is that any different from your employer demanding your Facebook password or your private email history? If you can be fired for refusing either of those demands then sure, they could fire you for refusing to give them your voting ID. But I'd say that's a completely different issue, wouldn't you?

Voter shows ID to election worker. Worker checks a box. Voter reaches into a giant lottery box full of generated IDs and uses that ID to vote. Later the voter can inspect the blockchain, find his ID and verify that his vote went to the right candidates.

I'm not saying it's a better system but I think there are ways to keep voter anonymity while also allowing the public to audit the result.

Maybe instead of representing solidarity with a silly hashtag it'd better for us all to exercise free speech by posting a picture of Muhammad. Not an overly offensive picture either, a simple stick man would do.

This craziness isn't going to stop until the media and us people in general start standing up for the things that we're always claiming to hold dear.

Comment Wrong threat maybe? (Score 1) 580

Maybe this has more to do with the threat of releasing more information "if their demands aren't met" than it does the threat of physical attacks? Maybe there really was some backroom discussion between Sony and the big theater chains to scrap the release because of this?

Or maybe not. It's probably just stupidity.

Comment Different kind of risk (Score 1) 151

Maybe there wasn't a legal risk that would have held up in court. What all that legal council evidently failed to mention is the very real threat of crippling litigation that, while ultimately unsuccessful, could still wipe you out in the process.

I guess that's one thing separating the 'good' legal council from the 'best'. The former will stop at examining the laws, the latter will also examine all the ways the laws could be abused to achieve the same result.

because we couldn't possibly have good service from an ISP.

Don't most ISPs sell good service at a premium? I think that was the entire point with having poor service in the first place. The only other reason I could imagine would be to drive customers to the competitors, and that doesn't seem to make sense from a business point of view.

I have no imagination, so I have no idea what we might get in the future if we actually had the infrastructure to support it.

I can come up with a couple of additional usages for some /64s. One /64 could be used to harden your recursive DNS resolver against poisoning. The 16 bit transaction ID in DNS is way too small. The entropy you can get from randomizing port numbers help a lot. But you will still only get a total of 32 bits of entropy that way. Some have gone to great lengths to squeeze extra entropy into a DNS request, for example by mixing lower case and upper case in the domain. But that doesn't give a lot of bits. If you allocate a /64 to the recursive DNS resolver, you can put 64 bits of entropy into the client IP, which instantly gives you more than a doubling of entropy almost for free.

A modern OS is a multi user system, imagine if each user could get their own IP address. You could allow users to use privileged port numbers on their own IP address, and all port numbers on their IP address would be protected from usage by other users. You could do this by responding to neighbor discovery for as many IPs in your link prefix as you have users on the node. But a more secure and more efficient approach would be to route a prefix to each node.
