  1. century city "without a tracer" predicted this on Children's Watch Allows Parents To Track Their Kid · · Score: 1

    Century City was a lawyer drama set in the future which tried to look at future legal situations (think cloning, meddling with embryos to produce the "perfect" child, etc). Only eight episodes were produced in 2004 and four were never aired (including the one I'm thinking of; though they are (were) obtainable via p2p). One episode (Without a Tracer dealt with a possible result of this sort of device.

    Basically, every child has a tracer (linked to video/audio surveillance no less). The episode revolves around a teenage girl who was fed up with being watched by her parents and removed her tracer, at which point the parents panicked because she'd apparently vanished. IIRC she hired a lawyer to get a ruling to "allow" her NOT to wear the tracer.

    Their point was that this sort of device, whilst well-meaning, can become intrusive. I think (and the drama hints) that the tendency will be to rely on devices, further abdicating parental responsibility. Furthermore, I wonder if anyone's considered whether this would make the wearer EASIER to target, should the ID for their device become available, e.g. to someone wishing to kidnap a child for extortion.

  5. pure economic sense = not surprising on Value Propositions of Current CPUs Put to the Test · · Score: 1

    Im sorry, but this article shows nothing that isnt obvious from the economics of the CPU market.

    The time a CPU spends at the top end of the market is small compared to the overall time it is available. This time is also at the lead-end of its production when availability is small. Rarity (and demand) create a premium over and above the actual worth of the CPU.

    By the time other CPUs displace it, such as CPU will no longer be in as much demand and the manufacturer may have to drop prices below or close to cost to sell end stocks. Thus they take advantage of the novelty of top-end CPUs to recover their development costs in advance.

    Basically, new CPUs are overpriced for what they can do, and tail-end CPUs are underpriced, which is exactly what the article shows.

  7. Re:Because it's a pain on Linux on Why Not Use Full Disk Encryption on Laptops? · · Score: 1

    Who modded the parent interesting?

    Entering a password at boot time is not a viable solution. The computer has to be able to boot the OS to a login prompt, which will allow the user to enter their password to decrypt their personal files.

    Exactly how do you think FULL DISK encryption works?

    I've seen one or two of these in use (older bank-owned laptops). They prompt for a boot password before the OS loads. I imagine the disk encrypter has a driver which sits between the physical disk driver and the VFS layer (to which the boot-time key is given), though I suspect getting this key from the boot loader to the driver under windows involves some contortions. The TPM chip in ThinkPads is a better solution (here's TPM working FOR the hardware owner).

    First, you either have to give everyone that uses the computer the same password to boot the system, or you need to use a multi-key encryption routine, which might difficult to maintain as you add or remove new users.

    As for multiple users, the mechanism for HDDVD demonstrates a principle which could be used; a disk or volume key (single key) is used for the encryption, but is stored itself encrypted on a special boot partition. Multiple copies are stored, one for each user, encrypted with a different password for each user. This also allows corporate recovery should the user forget the password. Recall that changing the underlying encryption key for a partition would require re-encrypting the entire partition contents (therefore the key is very unlikely to change).

    Then there's the issue of users having to enter two different passwords (for security, you wouldn't want them to be the same) just to log in.

    Oh pity the poor users unable to get to grip with the concept of multiple passwords [/sarcasm]

    How many passwords do you think the average user has to remember? Do you think the people who need to have encrypted hard disks are idiots? (okay don't answer that last question ;)

  9. Re:Asimov (and Hollywood) got it wrong on Pharaoh's Gem Brighter Than a Thousand Suns · · Score: 1

    Needlessly abusive, and entirely misunderstanding the point.

    As someone who actually watched the full Horizon show last night, let me retell what the physicist (Boslough), who's field of expertise is big explosions, explained.

    A small object striking the atmosphere is more likely to explode than a big object. A single big meteorite will smash into the earth and leave a big crater. A smaller object may explode before it hits the ground, leaving practically no crater. A collection of small objects together (something like Matilda, which is described as a "rubble pile" asteroid) which fragments and whose fragments then explode, creates a fireball plume extending (in the case of the shoemaker-levi event on jupiter) around 300 kilometres back into space.

    Boslough computer-modelled a 120 metre meteorite exploding just above the earth's surface. The resulting fireball extended 80 kilometres back in to space. Approximately 10,000 times more powerful than the Trinity nuclear test in New Mexico.

    Applying some simple physics explains the effect. Shockwaves propagate faster in denser matter. A full impact imparts the bulk of its energy into the ground, which transmit the energy away quickly. An explosion in the air imparts the bulk of its energy into the air which, being less dense, transmits the shockwaves more slowly, and less far, than the ground. Therefore the energy is confined to a smaller part of the earth's surface (and most of it above ground).

    The penetrative effect is, as you noted, significantly less, but that's rather irrelevant. Big holes in the ground don't kill things; 10-mile wide fireballs at 1800 celsius on the surface do.

    For a suitable analogy, consider the fuel-air bomb, usually described as the most powerful non-nuclear explosive. It explodes above the ground, but does more damage above the surface than an impact-detonated bomb of comparable (or greater?) mass.

  13. why no scsi raid controllers? on RAID Controller Shoot-Out · · Score: 1

    RAID in PCs has been a hot topic and I suspect a lot of marketing has gone into products which the vast majority of people have no real use for (having a RAID setup being bragging rights).

    If you really do *need* a RAID setup, it seems stupid to ignore the SCSI angle on things, because SCSI RAID controllers are much more mature in features/performance/reliability and obviously aimed at a market which is less tolerant of cheap'n'nasty.

    I know that SCSI is a lot more cost and, compared to SATA, not all that much more performance for the extra money. However....

    More than a year ago I picked up 2x Intel SRCU32 (these are two-channel ultra160 scsi) from ebay for £50 each. I've found these to be very good cards. In addition to the usual BIOS interface they also have software consoles for both Windows AND linux (the latter written by intel), are supported natively in linux (2.4 - driver is called "GDT").

    The software console means you can configure your logical drives without your PC being stuck at the BIOS/POST stage. From what I recall a sync of a 3x72GB in R-5 mode took about 4 hours.

    Another nice thing about this controller is that while being 64-bit 66MHz PCI it is compatible with (and I am using it in) 32-bit 33MHz PCI. However a downside of such older controllers is memory. It requires unbuffered ECC NON-registered PC133 (also found on ebay - 4x128MB for around £20) which can be hard to find.

    I'd also like to add that while I was getting these on buy-it-now, loads of other people were bidding £100+ on Adaptec 2100S auctions, which is a 32-bit 33MHz only, single-channel card!

    Summary - please think before you go buying this sort of thing, and really consider all the alternatives.

    Okay, you've got some good points there which I hadn't considered, particularly considering my example of pasting URLs. I was wrong on that point.

    Some things I would like to take issue with, though.

    You're making spurious claims entirely unsupported by the law in question. Again, to quote from the law in question;

    I think you're misreading this. The intention as far as I can see is to prevent a defence of exemption. That is, to make the act of breaking in an offence (irrespective of target).

    From where did you get this assertion that unless it's secured, it's freely accesible by all? If I leave my bike unlocked, am I "publishing" it? Do I have to keep a lock on it all the time to "define authorised access"?

    That's absurd. Bad analogy. Physical property can't be published. Reading an essay you had written and left lying around would not deprive you of the essay. Even making a copy would not deprive you of the essay. Don't try to equate anything in the CMA with Theft, there's no parallel.

    So I'll refine my claim that anything on a website is published. Anything placed on a publically-visible website and requiring no subterfuge to view (i.e. on the front page, or reachable via a link or chain of links from the front page) MUST have been placed there with the intention that other people can see it (and with no control on who those people might be). The material has therefore been made public by the actions of the owner. This is plain common sense.

    The point I am trying to make is about intent and unauthorised. Reading CMA 1990 (1)(1)(b) and (c) makes this clear:

    (b) the access he intends to secure is unauthorised; and (c) he knows at the time when he causes the computer to perform the function that that is the case.

    It is impossible for a person to know that access is unauthorised if the material is publically visible (in a public place, e.g. on a website) with no access controls (subject to my capitulation above regarding a chain of links). Ergo no intent.

    This is where I make my claim that the court gets to decide based on the circumstances - the court gets to decide intent.

    You wouldn't get very far with this argument. Anything placed on a website is published. Anything published is public, therefore access is de facto authorised.

    Now obviously you can put access controls on a website. But then you've taken a step to define authorised access. If you give someone a username and password, you've granted access. If someone obtains a username or password without permission, that's unauthorised. If someone bypasses this access control (and this bypass would probably have to be non-trivial; so if for example someone could cut and paste a URL which went directly to the material without being prompted, this would not apply) then it is unauthorised.

    I personally think that "computer material" was a bad choice of phrase, and that "computer system(s)" is more appropriate. I cannot think of a way in which access controls could be devised which would NOT involve the owner of a computer system defining (at least implicitly) "authorised access". I'd make the assumption that in giving permission to put computer material on a computer system the owner of the material has agreed with the owner of the system on what arrangements are made for authorised access.

    If my reading is correct it means a court gets to decide what is or is not authorised based on the circumstances, which is the Right Way IMO. Putting every conceivable situation in the Act would either be draconian or prone to loopholes as previously unconsidered situations arise.

    The Computer Misuse Act seems to have been designed to encode the electronic equivalent of breaking-and-entering (offences 1 & 2) and criminal damage (offence 3).

    Denial of service is probably very difficult to encode in a similar fashion, since I do not see what *criminal* offence it would equate to.

    In this particular care, there is no essential difference between sending a million emails and sending a million letters by post - both would swamp the service, but equally both are simply making use of the (e)mailing infrastructure as it was designed. (Yes I know letters cost more. That's irrelevant - they require more effort to deliver, and are priced accordingly).

    Taking a different example, such as opening thousands of connections to a server with intent to deprive others' of access to it, I still can't see what equivalent physical world *criminal* offence has been committed. In this case an analogy requires many people, but what difference is it if a thousand people stand on the pavement outside a shop entrance effectively preventing other shoppers from entering, due to weight of numbers? Sure, the police can ask people to move on, which is the same as closing those open connections, no?

    Since most electronic systems only enact operations which have equivalents in the physical world, I do not see how it would be right to create a law which makes the electronic equivalent illegal, when the physical original is not. This use of legislation creates the likes of the DMCA.

    The Computer Misuse Act is a rare example of a really *good* law which is (1) broad enough to capture most offenders (2) easily tested for applicabilty i.e. not complicated with exceptions, extensions, etc and (3) not so vague that it is open to abuse.
