What we need is a public key authentication scheme with the possibility for normal users to delegate their identity to some trusted third party to which they hand their public key (like with OpenID). I think this would be the best of both w

Something along those lines that I'd really like to see (or maybe create someday) would be a decentralized virtual universe. Minecraft and such games are usually run on a server which is under someone's control; it would be funny to have a

There is a difference between knowing that the message arrived in the recipient's inbox, and knowing that the recipient has opened the message. See http://en.wikipedia.org/wiki/Return_receipt#E-mail (DSN versus MDN). MDNs are not a very g

If you're able to use an online trading service, reasons 1 and 2 don't really hold, unless BitcoinDeals' margin is less than that of trading services (which would be weird).

Maybe, but it could still provide useful competition in a market which desperately needs some. (No, two players are not enough.)

Okay. I understand what you meant now. I see this mostly as a consequence of tagging: since all the messages are in the same store, it makes sense to get messages from the same thread no matter the choice of tags you're viewing. I think it'

These badges encourage people to click on articles, not necessarily to learn anything from them. Maybe they will still learn, but maybe it will encourage them to skim (even) more. You can sometimes obtain very unexpected results if you prov

I agree with you. It seems like the basic concepts are neat and clean, but that the interface to it, and the vocabulary, is counter-intuitive. The article really gives me the impression that git-reset can be used to do several vaguely relat

http://www.thanksno.com/ , which inspired this service, is intriguing. "I can't bring myself to tell you, so I'll use this webpage to tell you instead"? I'm not saying it does not make sense, just that it's a bit funny when you think of it

A good way to check if does the right thing is to make sure it does not depend on the security of DNS. Is this the case? (I'm still trying to find out.)

In which way? Could you elaborate?

You can keep the master copy at home but do (encrypted) backups on the cloud. I find it much more reassuring than the other way round (put everything in the cloud, maybe backup locally every now and then).

You need a lot of energy (cynicism? doublethink?) to be able to see such a pointless exercise as an opportunity for training. It might be the optimal thing to do, but it is quite hard to ignore that part of your brain which tells you to avo

My experience (in computer science, ymmv) is that a vast majority of researchers would agree that, with the Internet, the profits made by journals are excessive relative to what they do (ie. what they actually do, not what they outsource to

If you only have a limited collection of images to pick from, then bots could get decent scores by picking at random. A better approach might be to ask users to pick matching images (ie. 2^N possible choices).

This is a pretty good excuse, actually. DNS means that your identity is still in the hands of someone else. The only identity that you can really own is an asymmetric encryption key, but it won't allow people to find you.

Decryption is not about finding data which is inside something, it is about making sense of data you already have. Forcing someone to decrypt something is asking them to provide a plausible explanation of what the data means. Do not get con
