What's the O(n^2) connection?

I thought that in America an "egnineer" was a train driver.
Can we please not have "artists impressions" as the headline images in stories like this?
They distract from the actual science.

Your switch needs "port morroring".
I.e. you need an ethernet switch connected to (a) broadband router, (b) wifi acces point, (c) PC, configuured so that port (b) is mirrored to port (c).
This isn't easy if you have a combined wifi+boradband box, as most people do, unless that has a mirroring feature itself (which it probably doesn't). And the cheapest ethernet switches don't have port mirroring.
The alternative is to have two network interfaces on your PC, and to make the PC itself a bridge that the data must traverse between the broadband internet connection and the device of interest.

That's completely doomed if there is any significant DC component in the load, e.g. if there are devices with half-wave rectifiers, or full-wave rectifiers that are asymetric in some way.
To be fair they do have significant advantages over current transformers, i.e. linearity. And a good electronic meter should be more accurate than a mechanical one. But a cost-reduced electronic meter can clearly be crap.

Very much so, I was there.
> The point is that its not that easy to catch and shut down.
These guys were selling their services to legitimate businesses. You catch them by asking the businesses that are promoted in the emails who they paid to send them. Much easier to prove in court if you have a witness who says "we paid them to do it", rather than evidence involving IP addresses.
The aspect that I find disappointing is that he was in business for long enough to make a million dollars before he got stopped.
Ideally, I'd get one spam email and forward it to the authorities who would act immediately to shut down whoever sent it. In practice, the reaction to such reports is "you probably signed up for their spam but forgot".
Re: IPv6 usage soaring?
> ISPs which have enabled ipv6 like Sky and BT.
Well, BT have recently enabled it for users who have their newest router. Mine is 5 years old, and is unlikely to be replaced any time soo; it says: "IPv6 will be disabled on your BT Home Hub and BT Broadband Network until supported by future services"

Right now the bastet and adventure demos are working for me but nano is down.
They have deliberately low max-session limits...
I did consider doing persistent sessions, but on reflection I decided that it's better to do that at the next layer down i.e. using screen. Then configure Anyterm to invoke screen, rather than "ssh localhost". I should probably mention that in the docs.
There is no sensible way to do key-based auth. One-time passwords of some sort might be the best alternative. TBH it's fundamentally not well suited to situations needing more than modest security.
It's now 11 years since I wrote Anyterm, the first terminal-on-a-web-page:
There are some demos there, but you'll probably crash it if you all try at once.
It's open-source (GPL) and still maintained - I just added IPv6 support a few days ago.
For those of you asking "why", the main answer is so that people who find themselves behind an http-only firewall can still do command-line stuff on external machines.
My implementation was largely constrained by the technology available at the time (and the code still has lots of work-arounds for hopefully long-since-fixed browser bugs). It should be much easier to do today if you start from scratch.
Realistically, few people are going to follow this sort of advice and throw away products that, as far as they are concerned, are still working correctly.
So what is the real-world solution, that allows the net to function smoothly despite billions of vulnerable devices being attached to it?
Re: Quote from the video
"I am curious. How many foreign sextortionists have been convicted targeting for UK citizens?"
Maybe some; according to http://www.bbc.co.uk/news/uk-38150313 :
"Last year more than 40 arrests were made in the Philippines in relation to sextortion and there is one ongoing international prosecution connected to one of the suicides reported this year."

Re: Use the all purpose tool
By that logic, the entire article could be simplified to "Neo Technology has released Neo4j 3.0" and we could just use Google to find out the rest.
Some clue what "neo4j" is in e.g. the first paragraph might be useful.

Dabs was truely the worst customer service I ever got from any retailer ever.
Many of the others I won't buy from because of the constant deluge of spam that continues daily a decade after I bought from them just once.
I've recently stopped buying from Amazon after they charged me £70 for "prime" that I didn't ask for (presumably I forgot to not un untick the 'no, I do yes not no do don't want to not not not join' box).
It's a shame there doesn't seem to be a retailer who can just get it right.

Re: They gave him their password
In your car insurance example, the insurance company are not saying that stealing the car was legal because of where you left your keys; they're only saying that they won't pay out. The theif, if caught, would still be convicted.
Re: "behavioural marketing automation software"
> I don't much care which one wins, and rather hope that both lose.
I think I first heard that said re Mohamed al Fayed and Nigel Hamilton.
“We want to send a clear message to other firms that this type of law-breaking will not pay.'
On the contrary, the message seems to be that you can make a million pounds and keep £650,000 of it.
The fine is less than 1p per call, which is even more pathetic than the other recent ones. As a start, I'd like to raise it to at least as much as the fines for littering, parking etc.
And temperature! Don't forget temperature! Charles' law and all that.
Maybe we need an el reg "standard temperature and pressure" ? Suggestions? Improvements on; "as warm and squashed as a good boozer on a Friday afternoon".
How about this idea:
"You trustees are each sentenced to a fine of £100,000, suspended for 10 years.
"During those ten years you will be supervised by a probation officer who will make unannounced visits to your premises. If they find that you are storing your patient data in a system from which it may be copied-and-pasted or otherwise exported in bulk, or if they find that your email system is configured to allow messages to be sent to large numbers of recipients without multiple levels of confirmation and a time-delay, you will be liable to pay the fine in full."
Less than £2 per call. Pathetic.

Not developers who are trying to write portable code.
I fear Apple is unlikely to support this, as they have their "metal" language which does a similar thing. So for cross-platform development, you're probably still stuck with OpenGL.
Legislating about this is as likely to change anything as increasing the fine for littering.
For once, a technological solution might be the most effective. Presumably the military must have some ideas; they must have worked out that dazzling your opponent with a laser was a good idea long ago, and worked out how to protect themselves against it.

No - though I can understand why you might think it would be. See http://www.usb.org/developers/docs/devclass_docs/ for a list of classes of device that are standardised.

How much use is Bitcoin getting for purposes other than ransomware and drug deals?
That's less than £10 per complaint.
How long does it take to prepare and file an ICO complaint? OK, I guess this does come out at better than the minimum wage, but not by much.
I gave up complaining long ago. The fines really need to be 100X or 1000X larger in order to be worthwhile.
I find it interesting that they find this a better economic trade off than either (a) parachutes and fishing it out of the sea, like the shuttle boosters, or (b) gliding, perhaps using some sort of air-breathing engine. It would be interesting to hear how they decided on this method, despite its obvious challenges.
