Re: Silly idea
Your metallurgy must be longer ago than you realize
Fair cop guv.
Airbus has introduced laser welding on aluminium sheets long ago for the A380. With the right alloy and right welding parameters, you get a better strength-to-weight ratio than with rivets, which are a pain from a production engineering point of view.
Rivetting is a pita, not just for production, it can be a source of corrosion leading to fractures during the working life of the aircraft too.
And I take your point about laser welding on Airbus products, although that's quite a lot of qualifications for what turns out to be a relatively small part of the A380's fuselage. That being said I too expect the proportion will only increase.
However, imagine having to laser weld every dot of the structure in 3d as you print it. And when it comes to the jet engine turbine blades... after you sir!
Re: Silly idea
When it gets to the stage where "ink jets" are in fact "atom jets" then you might have a process that could produce viable aircraft. Until then 3d printing for most aerospace applications, without significant treatment regimes afterwards, is just plain not going to work.
Those treatment regimes (annealing etc) would lose you most of the convenience of printing anyway. It's been a little while since I did any serious metallurgy but I hate to imagine the physical properties of aluminium that has been ink jet deposited. Consider the fact that planes use rivets rather than welds to hold them together because welding weakens the aluminium alloy too much and you get a sense of the problem.
The degree to which the alloys in aircraft depend on strict atomic-crystalline arrangements on a large scale for their structural integrity is very impressive especially when you realise you bet your life on the fact that it is so and will remain so for the duration of your flight let alone the lifetime of the component.
Presumably the more these stories hit the press the less actual outlaws etc actually use these services for anything significant. So the more the govts trawl these sources the more they are focusing on innocents and the less they are gaining useful intel on actual terrorists.
These broad tools appear only to make the "security" forces jobs harder in the long run.

Re: If you still use a 1024-bit RSA key such as PGP, it's time to start using ECC-based keys
Why downvote the parent? It's an absolutely valid point. If you disagree then please provide some links to alternative mainstream ECC-enabled PGP-type applications.
The plan was for "a sealable 530ml container purchased for £3.50 from Tesco" according to previous coverage of this mission. But I agree, either the Lego hero is actually larger than life in real life (there's something to mull on over a (real life) pint) or else Tesco ought to be had under advertising standards/mislabelling.
Re: How the board laughed....
Settling out of court isn't sending a very strong message to either Verizon or other companies who are either currently engaged in similar behaviour or contemplating it.
As far as I am aware there was no court action, just the FCC investigation and the resulting conclusions which were accepted by Verizon because they paid the fine. That is quite different to settling out of court when a case has been brought.
Re: How the board laughed....
The financial cost is not high for them, as you point out, but management have very publicly been found to be breaching the rights of their customers and admitted their guilt by agreeing to pay the fine. That is still serious.
Verizon is not a company that can just dissolve and come back again under a new brand. They need somehow to make amends. Perhaps it's too much to hope that it won't be by just sweeping it under the carpet...
They say they added tweets to simulate clean SMS data. Well done!
They cleaned up 200,000 tweets to act as an additional source of non-spam. That is additional to the non-spam they harvested from the cellco's network.
Did the cellco concerned get permission from all the customers concerned before using their private non-spam messages in this research?

Re: That name...
Not sure it's confusing, it just makes clear where the code has come from. "Web" with a lightweight GTK interface promised for the RPi's hardware combined with the preference for a name with "pi" in it somewhere makes the choice obvious.

Re: Dumb question here
Most routers don't use https for admin logins, so if someone has cracked your WPS and is listening to all network traffic they can scrape your admin password. At which point all of the above warnings are true.
The same thing applies to mac addresses because they can be spoofed quite easily. And if you're listening to traffic then you know which MAC addresses to try spoofing.
The WiFi range thing is a very useful limiter on your network's exposure. However there are many easy ways to boost signal strength (eg the infamous Pringle can method) and attack a network from otherwise unfeasible distances. Just because your iPhone can't see your home network halfway down the street doesn't mean it's impossible to access your network from there.
Re: Just switched off WPS
<big bad wolf>
All the better to hack you with!
</big bad wolf>
If I'm not flashing with DD-WRT or OpenWRT then disabling WPS is one of the first things I do with a new router.
I'm obviously out of touch, though, because I had thought WPS was well known to be extremely dodgy already. Did someone manage to fix it for a while?

Balanced sound bite
> Finding the balance between privacy and surveillance is probably never going to be sorted in our lifetimes. It's a tremendously complex and convoluted issue, and it's questionable if the intricacies can be covered in a handy sound bite.
If/when we find the balance then a handy sound bite becomes a possibility, useful as a point of reference. Until that happens sound bites only represent a particular point of view.
Also, I'm not sure that the issue is convoluted. I think people's understanding is generally convoluted and often confused or inconsistent because the issue is nuanced.

"Disingenuous"? You're going with that?
"If they're making out that the data is protected and secure that's a little disingenuous because if they want to operate a business here, that'd have to comply with demands from the authorities," said Jeremy Goldkorn
It's more than disingenuous, it's the lie that everyone swallows when they sign up for cloud-based anything anywhere, not just China.

After all, auntie June is probably not going to have the elite hacker skills necessary to discover the undeleted files on the (emulated) sdcard. So you're safe for now. But only until she sells it on eBay for ££.99 (excl p&p).

Re: He's right! PGP sucks to use!
Its practical use is that it serves as a working system for many tech-savvy types, and also as a standard for other systems.
PGP was invented years ago and it was an enormous step forward, even though it was as tough to use then as it is now (in fact tougher - ever tried using it on a 386?). The thing is that the problems it set out to address then have only become worse in the intervening time: now there is not just the concern that it is possible to exercise mass-surveilance on populations in the "west", but the proof that it is in fact happening.
I don't know what the next big step forward will be or where/who it will come from, but I do know that it will need to give us at least what PGP does. Otherwise it won't be a step forward, but rather backwards.
The experts tell us that cryptography is hard and good cryptography is even harder. From my experience I would tend to agree. The question is, is it worth it? And attempting to answer that question leads you on to other rather bigger questions.
Re: Not saying PGP is perfect
> And how do you trust an email or key server?
That's what the fingerprint is for. You use it to verify that what you downloaded is actually correct.
Re: Not saying PGP is perfect
You don't need the whole certificate/key in a qr code, you can send that as an email attachment or download it from a web page or key server. The qr code would be useful for the key fingerprint though, which should be much more manageable. You would then use the fingerprint encoded in the qr code to verify you had downloaded the right key.
Re: He's right! PGP sucks to use!
It might suck to use for all the reasons he gave, and yes SMTP sucks because it was designed without security in mind, but there is one reason at least why PGP absolutely rocks:
You can use it to encrypt a message to send via just about any medium. And you can verify that security independently of the infrastructure you used to communicate.
As soon as you start to build a monolithic "secure" system you lose that independence, which is a big loss.
In every secure system I am aware of (and I should say that I in no way consider myself an expert in the field) there is always a trade off between convenience and security. You can have more of one but it means less of the other. If this guy has come up with a way of increasing the convenience without losing any of PGP's security then I'm all for it, but if he's advocating the opposite I don't want to know.

That was the most worrying part of the article!

Probably best not to turn the microwave on, unless you want to burn your phone... but that usually means something different.
Re: We need IP6
We can't be too prolific with our IP versions. The version field in the IP packet header is only 4 bits long = a maximum of 16 versions ever without breaking compatibility completely.
> geeks who want to do it cos its cool to have a v6 connection from your bedroom
Yes, because when was the last time a geek in their bedroom changed the face of the internet as most people know it?
Re: You don't need NAT for IPv6
Yes. If it does NAT it is, to all intents and purposes, a firewall.
And as to latency, which do you think is quicker/less resource intensive:
NAT: checking whether a packet is allowed to cross the lan/wan boundary, tracking which ones do and rewriting the address and port number on all of them.
IPv6: checking whether a packet is allowed to cross the boundary or not and forwarding them essentially unmodified if yes.
Yet another reason to demand a device with a removable battery from your smartphone vendor of choice.
IOW be afraid, be very afraid
So presumably this doesn't necessarily mean that every domestic router is pwned, but certainly that just about anyone can be.
I make it 21, not 23 as the article says. Or are there two extra ones hiding behind a controller chip on on the other side?
Re: Can you turn it off?
It's called a tablet. But then you still need a mobile for voice, so it's a catch 22. Unless of course you can make do without GSM/POTS in which case VoIP/Skype may do it for you.
