  1. Re:Duplicating SIM cards on 3G Notebook In Review · · Score: 1
    Under GSM, you'd have to duplicate the SIM rather than the phone. There is an "official" way to do this, whereby the phone company creates a new SIM for you with the same MSISDN (phone number) but different IMSI (SIM number - the phone network actually works on the basis of IMSI rather than MSISDN). A few companies offer this, mainly to make certain types of car phone easier to use.

    It's also possible to crack some (but not all) SIMs to get "Ki", the shared secret. Having done this, making a duplicate SIM is fairly easy. This will only work on networks which use the COMP128-1 algorithm to generate the session authentication and encryption key. This algorithm is not a part of the GSM standard, and does not have enough entropy, which means it's vulnerable to brute-force attack in a few hours. Most GSM operators avoid COMP128-1 for this reason.

  5. Re:Live with it, its not going away on AT&T Forwarding All Internet Traffic to NSA? · · Score: 1
    I live in the UK. Yes, the current situation is worrying, but we do only hear one side of the law on this. A while back I was in the happy position of telling an American company that our lawyers advised that it would be unlawful for us to provide certain information about our users, precisely because of the notorious RIPA (Regulation of Investigatory Powers Act) to which you refer (Part III). This specifies the circumstances under which you can provide information to, and hence excludes all others: in fact that was one of the reasons for bringing in the act. I believe (IANAL) that AT&T's action would be unlawful in the UK. Even if it were authorised, 28(2)(b) requires that the interception be proportionate to the purpose.

    I don't want to whitewash RIPA, OTOH - for instance I've just noticed:

    28(3) An authorisation is necessary on grounds falling within this subsection if it is necessary-...
    (f) for the purpose of assessing or collecting any tax, duty, levy or other imposition, contribution or charge payable to a government department;

    For GSM, the network will only ping it every few hours. Other than that, the network doesn't care which cell you're in within a region, as it will broadcast a request to get in contact over a region when it has an incoming call. However there are location based services which do work as you suggest - actually I believe it's a silent SMS which is used to trigger the phone to get in contact. LBS seems to work pretty accurately now - about a hundred yards, I think, in the town where I live.

    Disclaimer - I work in telecoms, but not this area.

    As I understand it, they were demonstrating in Parliament Square, which I understand to be illegal because of the danger of rioting.

  18. Re:Psion 3 on What Was Your First Computer? · · Score: 1
    Ah - the first I owned, though far from the first that I used (a Modular 1 with core memory). I used my Psion 3 for DTP for a church address book. As I remember it, I entered the addresses into the database, exported to the spreadsheet to sort to alphabetical order, then exported to the word processor for formatting and printing. All in 256kb of RAM and no SSD storage. Very much a real computer. I loved the way the 3 and 3a acquired a polish through long use, and the elegant design of the hinge mechanism.


    I later bought an MC400 - the early "laptop" variant of the Psion 3 with a touchpad, four SSD slots and a simple windows interface. I've never used that one in anger, but it's a fun machine.

  19. Re:Hot air on Super Bowl Footballs Get The DNA Touch · · Score: 1

    I think what they've done is to splice in the "GFP" (green fluorescent protein) gene. This is derived from jelly-fish and is commonly used as a debugging tool to test whether a vector (a virus modified to transplant genes) is working before they add the new payload. Even so, the DNA will not glow of itself, so I'm finding it difficult to see the point.

    An eight-hundred year old wooden church is impressive. The place I rave about is the Pantheon in Rome. In its present form it was built in 150AD, with the main part being a cylinder about forty yards across, surmounted by a concrete dome of the same diameter with a hole at its centre. The building is still in near-perfect condition and is used as a memorial church.

    Well, it's a matter of usability. Studies have show that the dual-engined concept of the Atlas is easier to use for the first-time rocket scientist. The five-engine (five!) of the Saturn F1 is intrinsically confusing in those "which engine did tech support say to shut down?" moments in the control centre. Contrary to propaganda, there's native support for strapping on additional boosters if the experienced user absolutely insists, although I would argue that this still detracts from the basic usability.

    Handling of exceptional conditions is less intrusive than the Saturn V: instead of an escape tower distractingly popping up over your work, you get a graceful pogoing on the launch pad. Yes, there are a few payloads that aren't yet available for the Altas V, but that's only real retro-gear dating back as far as the 60's!
