Comment Re:Be careful of the term "terrorist attack" (Score 1) 737

Given the speed at impact: ~800 km/h - ~500 mph, the odds of anyone surviving the actual crash are probably extremely remote. The largest body parts they found were apparently "the size of a brief case" - and the size of the largest debris that of "a small car" (whatever that means).

The weird thing is, apparently the procedure when one of the pilots leaves the cockpit is for one of the flights attendants to go inside the cockpit temporarily until he returns, I imagine specifically to try and prevent such a scenario. If that's true, they probably simply didn't apply protocol, especially for such a short routine flight. Hopefully this event will make sure it will be applied in the future (still, can't wait for planes to be entirely remote or AI controlled to avoid this kind of things).

Maybe the pilot was extremely depressed (and incredibly selfish - although depression may have been so strong he didn't even care anymore), and decided he couldn't take it anymore. Or maybe he played kerbal and decided to try some good old lithobraking :-p (too soon ?)

It's a Python frontend to the wireshark filters accessible from a GUI console. Whoop dee doo !
That being said, it also includes some features for tracking continuous sessions based on L7 filtering, provides a limited GeoIP resolution, and so on - and it at least provides a framework for developing more advanced analysis.

As others have said since this release, it is at least an open source, base framework for developing more advanced stuff, and it provides library integration points for other software. As basic as it is, it might provide a common framework for an open development of an advanced traffic analysis tool that'll be open (after careful reading of the code, any relatively good expert would be able to provide a similarly capable code in a matter of days and probably has, as an interesting case study/exercise previously - I know I did, limited to HTTP analysis but still). That can only be a good thing, if only to regroup efforts in that direction to provide a universal traffic analysis tool for forensics and so on.

Any code being released open source is always a plus :-) It's nice to see even the US army realizes this.

Comment Re: Relays, not exit nodes (Score 1) 80

Reading my post again, I should add: tor (very) likely works, as long as it is used for accessing hidden services, staying inside the tor network. As a bridge to access the general Internet, given the wide scope of monitoring by the NSA and co (shit, given the Snowden docs they seem to be able to view almost the entire network), there are several signs that timing analysis could semi-reliably de-anonymize specific users for a limited time.

how does the DoJ know what percentage of ANYTHING is going through it

That's an easy one: they make that number up, to spread FUD about it. And read the article I linked, BTW (and the source it links): the number in question has been easily disproved, with a relatively simple analysis of hidden services' hostnames resolution. Tor is not the USA's tool - it is an open source, publicly available software that was originally financed by part of the US government, period.

I realize all the Snowden revelations have made lots of people a bit paranoid (which is a good thing, mostly); but the fact is, it is extremely unlikely that tor is compromised in any serious way. Barring human error, tor works, mostly - there are some attacks possible, and there are demonstrated attempts by the NSA and others to compromise it (with some extremely limited results, both in their scope and in their duration); however, I have not seen any shred of evidence suggesting that it has been compromised in any serious way. This growing meme that "tor is broken for good", and the larger one that "if it's connected to a network, it's accessible by the NSA" is simply bullshit.

The thing is, in all likelihood, tor works. GPG works. If you encrypt something with GPG and the key is not available to them, even the most powerful security agency on the planet will not be able to read it. The advances both in basic mathematics and/or computing required to break those are so extreme that it would be very, very hard to hide it. And nothing in the Snowden leaks has suggested that those have been broken - quite the contrary, in fact, since several of the revealed documents suggest that tor and the growing encryption usage are a serious problem to those agencies.

That doesn't mean that it'll stay that way, mind; personally, I think that some sort of quantum computing might be in reach of those same agencies in a few years (and they are dumping and storing all the encrypted, non-breakable traffic they can in the meantime, I imagine waiting for this day) - and even that personal opinion will seem paranoid and far fetched to most experts in the field. But in the meantime, the most likely hypothesis is simply that those encryption algorithms and protocols are still secure. If you have any shred of evidence that is not the case, please link those - I'd genuinely appreciate it.

And finally, about Ulbricht and the other dark net markets taken down more recently: all of those have been clearly linked to human error, from corroborating testimonies from several parties. So sure, you can believe that this is entirely parallel construction, and you can also believe that Obama and most of the five eyes countries are bitching about encryption more and more to present a plausible deniability front while decrypting everything in the background; but right now, once again, there's nothing public even hinting at that.

Comment Relays, not exit nodes (Score 5, Informative) 80

It should be noted that those are relays, which transit data inside the tor network, not exit nodes (which provide exit points to the general network and can be a large risk for their operator should any illegal content be accessed). Relays still help with the general obfuscation of the network as well as for hidden services, though.
Apparently, Mozilla is considering eventually deploying exit nodes as well though.

Finally, for those that will scream "child porn", it should be noted that a very, very small minority of tor traffic is actually linked to that type of content, despite what the DoJ says; the best estimates from the tor project is around 1.5%. This move by Mozilla is a good thing - amongst other things helping countless defenders of freedom in oppressed regimes speak up in safety.

Clarificiation on the IP Address Security in Dropbox Case 152

Bennett Haselton writes A judge rules that a county has to turn over the IP addresses that were used to access a county mayor's Dropbox account, stating that there is no valid security-related reason why the IP addresses should be exempt from a public records request. I think the judge's conclusion about IP addresses was right, but the reasoning was flawed; here is a technically more correct argument that would have led to the same answer. Keep Reading to see what Bennett has to say about the case.

Comment Re:plugin-container.exe (Score 1) 400

I guess it could - firefox's plugin-container is compiled for the same arch as the browser itself though (so if you install firefox 32 bits, you'll get the 32 bits plugin-container).

A quick search seems to suggest it would be theoretically possible to have an 64 bits firefox talking to a 32 bits plugin-container loading, say, the flash plugin; it appears however that that would require an IPC bridge between both process to perform some sort of conversion (this suggests that somehow the way both process communicate is arch dependent ? I don't know enough about xulrunner to confirm).
There's a compatibility layer that apparently exists to do exactly that: nspluginwrapper.

Myself, I tend to avoid the headache and simply run the 32 bits version of Firefox even on an amd64 system.

Comment Re:Any suffiently advanced tech... (Score 3, Insightful) 986

But the "inventor" hooked up the meter, no?

No. The entire experiment was setup by the researchers themselves; the lab has no connection to Rossi, and none of the equipment came or was set-up by him. His only implication was to be here for the initial "fuel" insertion and the ash retrieval at the end, while being monitored (though that's more than enough to be suspicious of the alleged transmutation and suspect some sort of swap - still, it doesn't explain the excess energy).

Comment Re:Hoax (Score 3, Interesting) 986

Oh, he says words which he calls an explanation, but they fly in the face of already-understood theory, and he offers no explanations about why already-understood theory is wrong.

Agreed on this - it should be noted, though, that Rossi is not the only one that claims excess energy and transmutation using these kinds of mechanisms; look up for example the MIT NANOR devide (a small scale device that put out excess energy for more than one month straight), or the Mitsubishi transmutation claims in similar devices (later replicated by Toshiba). There are also other companies claiming similar things (Brillouin for one).

If this thing works (and that's obviously a big if), then I'd suspect Rossi discovered this mostly by accident, and that he has no precise idea himself of how it actually produces energy. IIRC, the few initial theories proposed are based on the idea of nano-scale lattices with trapped hydrogen inside; combined with some sort of excitation (EM usually, although not the only one that apparently produced some results) allowing somehow for the Coulomb barrier to be overcome at those scales and for a limited-scale, radiation-less (how ?) fusion to occur.

This is of course all pretty impossible given our current understanding of physics so if it does work somehow, it's wonderful news, even if it cannot be harnessed for energy; because it might lead to new, exciting physics.
