Do you get an infinite comment loop?

On Android, if I click on a link in an e-mail to a response to a comment of mine it takes me to the Slashdot mobile site with the parent of my comment.

Scrolling down I get to my comment, then the reply, then my comment again, then the reply again, ad infinitum (or ad crash really).

I do not event get to the comments. The frontpage takes forever to load and cannot be scrolled.

In addition to this the author is blatantly ignorant about ssl and criptography:

If you possess DuckDuckGo’s cert, you can decrypt all traffic to DuckDuckGo

They claim NSA can decrypt all SSL traffic on a whim. They probably can obtain DDG private key if they want to, but that does not mean that anyone with the _public_ key can decrypt all SSL traffic directed to them.

True that, but agreeing on a password is a lot easier than comparing key fingerprints. A phone call, if you trust you can recognize your partner voice, could suffice.

You may not even need a sideband channel, the name of the place where you met for the first time would probably be secure enough for most purposes.

"You already use the internet, they should be able easily to associate your IP with your identity. "

only if you are a complete fool and use your home internet for most things.

they cant find me in the noise of a starbucks connection.

Unfortunately for you, the combination of browser plugins you use is basically unique (see https://panopticlick.eff.org/) and more than sufficient to track you.

AFAIK, you can't use OTR for 'disconnected' messaging, where one user is offline atm.

Actually, you can, even if it is a bit impratical. The original OTR paper (http://www.cypherpunks.ca/otr/otr-wpes.pdf) even discussed a way to use OTR with emails. Unfortunately that never gained much support.

There are ways to prevent MitM attacks. The crypto.cat people were working on an implementation of the scialist millionaire protocol (http://en.wikipedia.org/wiki/Socialist_millionaire) that would use a simple password, exchanged via secure means (read: in person) to validate the partecipant public keys.

It's relatively easy to permanently preserve all of mankind's knowledge, just pack it in a rocket and send it Oort-cloud bound. Well permanently as in astronomical timescales. The trick is to preserve all of humanity's knowledge in a way that's useful to humanity in the future.

Even if it was cast in stone, in large letters, most of the information that we could store is useless for another, more poignant reason: it is badly organized.

Let's say you are a survivor of some global catastrophe, you have been knocked back almost to stone age,. How long can you scavenge the remaining of our civilization to survive? At some point you will have to start to produce your own food and tools.

What do you know about farming? Herding? Metalsmith? Even if you were a farmer / breeder / blacksmith how far would you go without modern technology? Think about it: no pesticides, no medicines, no blast furnaces. You have to slowly and painfully start to rebuild civilization again.

How useful would the wikipedia articles on the subject be? And the books in a library? The information they contain is organized in a way that is utterly useless to you. The only thing remotely helpful are survivalist magazines and army manuals. But even those will not tell you how to rebuild technology, how to make a windmill, or a wool spinning wheel. How to forge tools and then use them to work iron and so on until you get back to modern metallurgy.

I really wish someone made the effort to organize modern knowledge so that all of the steps that lead from stone age to space flight were clearly identified and explained. We take way too much for granted, the process of rediscovering everything, of finding out how do you really get from zero to the internet would probably teach us something very important about ourselves and the road we have followed.

Comment Re:Stepped in a pool of radioactive water (Score 2) 319

Something seems maybe not quite right; wasn't there an engineer(s) who inadvertantly stepped in a pool of radioactive water, and got enough exposure to get skin burns? My google-fu is lacking, I can find references to the incident, but I can't find their estimated doses - I remember it being a big deal at the time, though...

Q: What if I took a swim in a typical spent nuclear fuel pool? Would I need to dive to actually experience a fatal amount of radiation? How long could I stay safely at the surface?

A: Assuming you’re a reasonably good swimmer, you could probably survive treading water anywhere from 10 to 40 hours. At that point, you would black out from fatigue and drown. This is also true for a pool without nuclear fuel in the bottom.
