Well ...

>> I've never found anything on the other side of the garden wall that was sufficiently amazing, or consistently stable enough to warrant all the effort.

It all depends on your needs.

For work, I wanted a WiFi scanner - verboten by Apple, available once jailbroken.

I wanted to use the Bluetooth GPS I already have - not on the approved list from Apple, works just fine with RoqyBT4 installed.

These were the two key things I wanted.

Then other things are a bit more subtle. SBSettings from Big Boss allows you to show more in the status bar - like the WiFi you're connected to and your IP address. That's useful for some of us, of no interest to others. It also gives a very useful option to swipe the status bar and turn stuff on/off (eg Bluetooth, Location, etc) in a tap or two.

So far I've not installed anything else - partly because Cydia seems to require the use of Google or Facebook identities, neither of which I have or have any intention of having.

It'll only work when ...

It'll start to have an effect when phase 2 kicks in. What few supporters of the tech are talking about is what smart metering is really there for - demand management. Not persuading us to switch a few lights off etc, but real demand management where people will think twice before putting the oven on for Sunday lunch, or putting a load of washing on.

When all the windmills stop turning (as they do in those calm, bitterly cold spells), and we've no nuclear left, and the coal stations have been shut down to meet EU legislation, and Russia puts it's foot on the gas hose ... Well we'll be short of lecky - anyone else remember the rolling power cuts of the 70's ?

What will happen is that lecky costs will rise - dramatically enough that few will be able to afford to use it. So magically, wind power will still be seen to be working, but only because people have turned everything off and are sitting in the dark. If that fails, then the smart meters allow a more fine grained remote turn off facility that can plunge individual houses into darkness and cold (yes cold, gas is no use if your boiler is switched off - and those with combi boilers will find themselves with no hot water either).

Government claims smart meters won't be compulsory - but I bet the disincentives (by way of vastly overpriced tariffs) to not having one will be huge.

Yes it's a big deal

>> Is an electricity shortage such a big deal anyway

OK, we complain as it is that the UK cannot compete with <insert foreign land> manufacturers. Now add into the mix that a business won't know from one day to the next what the energy costs will be, or even if they'll have any at all.

When the lecky goes off, or just goes so high in price as to be unaffordable, then the business has to stop production. Then what ? Will the employees say "no problem boss, we'll go home without pay and not complain" ? I don't think so.

So the business either pays staff to do nothing, or it quickly find it can't get anyone to work for them (without paying inflated wages to cover the dead days.)

Either way, the business finds it's costs vastly increased and becomes even less competitive.

The alternative is that many, many people will start fitting their own diesel generators - not too inefficient if you use heat recovery on them. So the mad rush to intermittent renewables will lead to even worse shackles on business, AND a rise in the use of local diesel generators. That will really help the economy recover, reduce CO2 emissions, and improve air quality ... or rather it won't.

For small loads, could use a UPS - but then you have a load of lead acid batteries to manufacture - and a round trip loss that will actually increase overall electricity usage.

Yes, the "smart grid" stuff is mostly about "load management" - more or less a euphemism for rationing. Yes, some things (like electrically heating water in a storage cylinder) can be fairly easily used to manage demand, but many uses can't. "Cup of tea darling ?" ... "Oh sorry, it'll have to wait until we can afford to boil the kettle !"

How about the original release ?

Part of the issue with the original release mechanism was the friction from the payload release. If all it needs to do is make electrical contact (or perhaps activate an optical switch) then it will be much more predictable.

And rather than adjusting the quantity of air, use a nominal amount and have a calibration run in the chamber. Put a scale alongside the pushrod, turn up the altitude, and then see where the rod gets to - that's where you fix the trigger switch.

Or, how about this for a DIY low pressure switch ?

You need a small chamber, across the end of which is a porous plate and a sheet of electrically conductive film. You suck down the chamber pressure to that at which you want it to trigger - and seal it. The film will be sucked hard down onto the porous plate - but because it's supported over all it's area, it won't stretch or burst.

Once the external pressure drops below that in the chamber, the film will lift off the support plate and start to ballon - which means it'll touch the nearby contact and trigger the circuit. Or you could trigger optically by various means.

As you've already built a very small hypobaric chamber (REHAB - if your experiments don't destroy it !), you'll be able to check the operating pressure before launch without needing to call in favours at the full sized chamber.

Re: Just to be clear

>> The problem with nuclear fission is the waste produced and its storage.

Correction, the problem with "currently used" nuclear fission.

And why do we only use low grade reactors that make lots of long lived waste ? Why do we insist on dealing with it now rather than leaving it for 100 years when it will be much easier and less costly to handle ?

The answer to both is politics - and in particular the "oh no it's nucular and must be bad" response from certain quarters. We've had the technology to built "better" reactors for many decades - better as in produce more energy from less fuel and have less bad wastes at the end. But there's only one word that gets people frothed up more than nuclear - and that's plutonium. Hence it's been impossible to build the better reactors because all those hippeis would be even more woulnd up and teh red top readers would blindly follow them in ignorance.

Re: MAC Address

Bear in mind that on some systems - particularly cable which is more common in the US than here in the UK - the MAC address of the cable modem is the primary access key. The cable modem is ISP supplied, provides an ethernet port, and the user connects their own equipment downstream from that.

So for that type of system, it is not silly to ask for MAC addresses which will be fixed and uniquely identify the subscribers connection - while an IP address may be more open to challenge where they are dynamically assigned.

Re: "for purposes of tariff comparison"

>> Variable charging rates are going to do nothing more for the customer than confuse him; turning hardware on and off depending on the rate requires significant infrastructure changes (and incidentally, I want to run the washer *now* not when the leccy say I can!)

And *THAT* is what all this smart metering is about. It will save very very little in overall consumption (government officials have already admitted as much), it's there pure and simply to allow variable rate pricing - also known as price based rationing.

You see, with all those windmills we are subsidising to be built, power supplies are going to get more and more intermittent. We are already up to 4 1/2GW of metered capacity onto the grid - and output can vary in a matter of an hour or two between "F**k all" and "nearly flat out". Not to mention, that many of our peaks in demand (like December 2010) coincide with extended calm periods when there's no wind.

This means other generators (most notably gas turbine) have to keep turning their output up and down to compensate - so they are having to do a lot more starts and power changes to compensate for variable renewables supplies as well as variations in demand. Of course, the very significant costs of this are external to the windfarms and so are cleverly not included in the cost of wind lecky. The "simple" answer from the pro-wind camp is one of the following depending on who you ask :

1) wave their hands vaguely and insist that the European super grid will deal with it as we can buy any shortfall from abroad. Except that is, when the rest of Europe is short of power because their windmills have stopped too and they've been too short sighted to build some more nuclear plants.

2) wave their hands vaguely and insist that "smart metering" will deal with it. What they really mean is the power will be rationed, and unless you have lots of cash then you will be forced to use power when the wind blows rather than when you want to. So when the wind drops, your lecky will go up in price to suppress demand. Of course, no-one (or very few) will admit this even though it is the only way huge quantities of variable wind (and other intermittent renewable) power can be accommodated with current (or likely medium term) storage technology.

And if that doesn't work, the remote turn off can be used to create rolling blackouts like I recall from the 70s. I know of more than one person thinking in terms of a small diesel genny with exhaust heat recovery ...

Re: What is Apple (supposedly) guilty of?

> It hasn't been proven yet

Err, yes it has - there's nothing top prove as all you have to do is read the contract where Apple require that the goods (and it applies to Apps as well as books etc) are not sold anywhere else for less. That means, if someone else thinks they can sell an ebook on 5% margin, they cannot discount the retail price - because the publisher will have contracted with them on an agency model as well in order to comply with Apple's contract.

This is sufficient in it's own right I believe since it prevents competition. SInce it prevents any seller setting their own price, there can be no price competition, and that means prices are highly likely to rise - and guess what, they did.

Incidentally, Amazon do the same thing. If you sell "stuff" on Amazon, under the T&Cs you aren't allowed to sell it cheaper elsewhere.

Re: Hear hear

>> My super told me that PETs had a lock on data collection in labs ...

Maybe not a lock (by which I assume you mean a commanding market lead), but I recall they were popular for one good technical reason ..

Fitted as standard on the back of the PET was an IEEE-488 bus (aka HPIB or GPIB) - although they used a cheap and nasty card edge connector rather than the quality ones in the standard.

http://en.wikipedia.org/wiki/IEEE-488

There were (at a price) many lab instruments with an IEEE-488 ports on the back, so it was easy to hook them up and send/receive commands/data. So it would be fairly easy to (for example) send a command to a power supply to set a certain voltage on it's outputs, and then read in the outputs from the device under test using a GPIB equipped voltmeter.

There were other computers that could do this, such as some rather neat jobs from HP - bet you can imagine the relative prices ! That gave the PET an edge.

There were lots of other stuff that would hook up to GPIB - printers, plotters, floppy drives, ... In some respects it was to connectivity back then as USB is now - and in between we've had the good (SCSI), the bad (pick any one from many proprietary systems), and the ugly (parallel port disk drives, yuck). I can think of 3 reasons IEEE-488/GPIB never became ubiquitous - it probably was "not cheap", it was probably seen as "belonging" to HP, and the cables/connectors were fairly bulky (but they were stackable which made daisy chaining very easy).

IIRC it was also fairly easy to program with as well. I recall "some years ago" getting paid for a data transfer job off a PET based system (running a database off floppy disks !). I borrowed an IEE-488 card for an Apple II and wrote a program to handshake like a printer and slurp the data to a file on disk. A quick report to dump all the data out from the database, "printed" to this other computer, then load into new database and job done.

Ahh, nostalgia.

But there's more. There were (from memory) three competitors for the desktop at this time. Two are well known - the PET and the Apple II. IIRC the third was the TRS-80. My memory is a bit vague from that long ago, but I think any one of them could have made it - but Apple won for one simple reason. When Visicorp brought out Visicalc, they looked at what was available and decided that Apple had the better specs - basically more memory with up to 48k on-board and up to 64k on an add-in card. Visicalc brought automation to spreadsheets (yes, they existed before computers and calcs were done by hand) and was snapped up by ready users (especially department managers keen to escape the tyranny of their IBM centric MIS departments). That meant sales of Apple IIs, and the others lost out. The rest, as the saying goes, is history - the TRS-80 disappeared into oblivion along with a myriad of others, the PET struggled along for a while (especially in niche areas such as lab work), Apple did "fairly well".

@Paul

> There are many people who bought Freeview dvb-t1 TVs which could decode such HD and didn't know they'd be stuck with SD

But that's an argument for OFT/Trading Standards/ASA getting involved and stopping what were blatantly misleading descriptions.

I can't get any HD channels as I don't have any compatible kit - but I do support having used it. You yourself make the point about OfCon failing to mandate DAB+ compatibility and thus leaving us stuck with the inferior DAB. In this case, putting HD on DVB-T2 has inherently forced all manufacturers (apart from the liars who sell DVB-T kit as capable of getting HD transmissions in the UK) to incorporate T2 receivers in HD kit.

They *could* have put HD out on DVB-T - but then people would be moaning about why the UK went with DVB-T (DAB) when we could have had the better DVB-T2 (DAB+) standard if only "the authorities" had mandated T2 (DAB+) compatibility.

Give it a few more years and I can't help thinking we'll start to hear talk of switching more muxes to T2 to get more capacity (adding any more muxes has already be ruled out, especially when the spectrum has been got rid of) - but that would really need T2 capability being mandated for anything sold as "Freeview".

As for transmitter power, as others have said, the actual power isn't as high as you might think, and when you divide that by the number of people served, the power/person is very low - many of the figures are under 1W/person. There is no way whatsoever that you could get the same service* to lots of people without using more power. Even if you have existing kit (end user routers etc) already running, the incremental power from putting the extra data through the system will probably exceed the savings from shutting down the transmitters.

And that's before you start talking non-cabled systems to support mobile users.

* Note service, not data. Where service means any user can pick any of the programs being transmitted.

Yeah right !

>> Any losses incurred by this kind of fraud would be refunded by Barclaycard, once the customer has jumped through the required hoops

And the required hoops ? No doubt prove the unprovable. They will claim that their system is secure (as they do with Chip&PIN), and therefore show that the transaction had to have been made with your card. Since you still have the card and it's never been out of your possession then you must have used it. QED - required hoops attempted and failed. I know someone who had his bank account maxed out just after pay day - and the hoops his bank made him jump through (how do you prove that you didn't make purchases in your home town ?) It caused him a not inconsiderable amount of hassle - and the Police were actively unhelpful and even threatened to arrest him for trying to get evidence preserved (he went to one place the card had been used to ask if they had CCTV of the purchase and could they preserve it - something the Police weren't prepared to do).

I too got a contactless Barclaycard - I too wrote to them and said I don't want it and **won't** carry it. Needless to say, they won't provide a card without, so I don't carry it (I have other cards without that). I was tempted to see what a few seconds exposure to 850W of 2.4GHz (standard domestic microwave) would do to the chip !

As for the "convenience", well I tend to find that it's convenient to hand over a small sheet of paper with a portrait of the Queen on it and/or a few small metallic tokens. They've served me well enough over the years, I can control the exposure to risk (I can't lose more than I'm carrying), and I've yet to find an establishment that doesn't take this old fashioned payment method.

Re: Rod vs Rail

You mean ... like a lot of curtain tracks ?

SImon Hobson

Apple's argument falls down ...

... on the simple question of ...

Why do they need a clause prohibiting the sale of a book cheaper elsewhere ?

The answer is simple, if it's cheaper at Amazon, then people will buy from Amazon and use the Kindle App - and Apple gets nothing while people are building up a library of non-Apple books. Such customers will have little reason to stay with Apple if they find another device they prefer.

By ensuring Amazon can have no price advantage, they can punt books to users who will see no incentive to go outside of the iTunes store. Thus punters will build up a library of i<whatsit> only material and so will be less inclined to go elsewhere in future - they will find that they cannot take their iBooks to any other device.

This is all about capturing customers and trapping them inside a walled garden so that they are less and less able to spend any of their money with competitors - that clink, clink noise is that of more bricks being stacked on the wall.

It's not just "air spaces" ...

It's not just air spaces like swim bladders and lungs. As pressure is reduced, gasses come out of solution. For an example of this, consider the liquid inside your unopened bottle of <preferred fizzy beverage>. When you release the seal on the cap, the pressure drops and CO2 comes out of solution to form bubbles.

Read more about the effects here :

http://en.wikipedia.org/wiki/Decompression_sickness

I think it's safe to say nothing from that depth will survive being brought to the surface - even if you allowed years for the decompression.

As for leaving lumps of steel down there, it's won't bother anything. In fact, some organisms will positively thrive on the tasty feast left for them - yes, there are marine organisms that "eat" steel.

Confusing names ...

>> There will never be a broadband only product

Actually there are ISPs (or at least one, Gradwell) doing MPF (Metallic Path Facility) lines where all you have is the broadband.

But does anyone else think the definitions seem designed to confuse ? At least the descriptions in the article are confusing - "broadband only" is actually a line connected to a BT phone port at the exchange, so the low rental is in addition to the "phone line" rental.

Re: International treaties?

You mean the Berne Convention.

http://en.wikipedia.org/wiki/Berne_Convention_for_the_Protection_of_Literary_and_Artistic_Works

Yes, I'd find it hard to believe that France wasn't a signatory, because if they weren't we'd have all sorts of "issues" with them. And this new law is completely incompatible with the Berne Convention. Two areas come to mind :

1) "it is prohibited to require formal registration"

This new law effectively imposes a requirement for your to register your 'opt-out' of losing control of your rights. Incompatible.

2) "all works except photographic and cinematographic shall be copyrighted for at least 50 years after the author's death"

Not any more, under this new law, (some) authors will effectively lose their rights within their lifetime, and the estates of deceased authors will also lose rights before the 50 years is up. Incompatible.

France would have to withdraw from the Berne Convention - and that would cause a s**tstorm of problems for them. It would mean no other country signed up to the Berne Convention would need to honour copyright on French works. And I'd expect (as another commentator said earlier) a sudden raft of "not to be exported to or published in France" clauses.

But so many common expressions could fall under this ...

Many years ago, I recall Mike Harding being interviewed or on some program or other. He told this tale of how he and a colleague found themselves being stared at in a restaurant for a a common expression. The restaurant was on a reservation in America - and the phrase they used ? That common (at least "oop north") was ... "I could murder an Indian".

In many parts that's an everyday expression that one could really enjoy a meal of Indian cuisine (ie a good curry). The obvious interpretation when taken out of context would fall foul of the same law.

I wondered how long ...

... it would take for someone to say it.

>> Unlikely the architects would have wanted to have opening windows because it screws up the aircon....

Indeed, I expect a large space like this will come with highly specified environmental controls - not just temperature controlled, but maintained with filtered, temperature and humidity controlled air. Anything else would be a terrible place to work.

Opening windows work in small room, but when you get to larger rooms then you have the problem that for people away from the windows to get any air, those near the windows get "an excessive amount" of air - typically they get frozen in UK climates.

Correct, aviation fuel is not taxed

>> As far as I and Wikipedia know, jet fuel is not taxed, not even VAT in the UK. This helps to reduce the airline bancrupcies. This is also handy for people with their own jets ...

The reason aviation fuel isn't taxed is because of international treaties - it's nothing to do qith reducing airline failures which has never been a consideration for the tax man. If (say) the UK imposed heavy tax on aviation fuel, there would be a big economic incentive for aircraft to arrive in the UK and only take on enough fuel to reach their next stop outside the UK - in principal they'd like to have just enough to land and taxi to the stand but no-one would push it *that* far*. They'd then fuel up outside the UK, cramming as much in as possible and minimise the amount they need to buy on the next stop in the UK.

* There are in fact rules on minimum reserves to be carries, but even with these, there have been incidents where aircraft have run out of fuel. Some of these have been due to errors (lookup Gimli glider), some just down to using more fuel than they expected. Running out of fuel during a flight is not generally considered a good thing !

Such is the cost of fuel to feed a large aircraft, if there is enough differential, airlines will re-route and/or add addition stops if that will reduce their costs.

Clearly there are significant safety issues if airlines are pushing things to the limits, and so there are international treaties that aviation fuel isn't taxed by any country so as to minimise such incentives.

Not only is this a source of envy to non-flyers, it's also a source of envy for those flying at the lower end of the scale where fuels (AvTur (for turbines) for non-commercial use, and AvGas (petrol) for all uses including commercial) is heavily taxed with fuel tax and VAT on top of that.

RE: Or just hide the SSID

>> If you don't broadcast it, it won't show up.

Wrong, so very wrong !

If you turn off SSID broadcasts, you can actually increase the number of packets transmitted with the SSID in them. You also increase the workload on both your access point and attached devices as attached devices will keep actively looking for other bases with the same SSID rather than passively looking for broadcasts.

In short, "hiding" your SSID just doesn't, and it increases the amount of control traffic required to make the system work.

But I agree with the others, this is just typical Google - "we're going to do it, and as a breadcrumb tossed to refusenics we'll allow you to ask us to remove it if you actually find out there's a away to ask". In my case, I can confidently predict that if I changed my SSID as suggested then it would ... have absolutely no effect whatsoever for a good many years. Google streetmap cars have only been round here once, and I doubt if they'll come by again any time soon.

One fairly useful strategy would be to use a system where the MAC address can be changed, and script something to change it very frequently and randomly. Once you change the MAC address, then the data they have becomes useless. Not to mention, it increases their storage requirements keeping track of all the random base stations that do get reported by automated snitches.

SImon Hobson

Err, that's it !

>>> ... is a US law ...

Simple really, if you want to be able to sell your product in the USA, you have to comply with their laws. In effect, that means you need to be able to prove to your purchasers that you've complied, and that all the components you've used come from suppliers that comply, and that their suppliers comply, an so on all the way back to the source.

So the tantalum processors are taking the view that since they cannot **prove** the provenance of the ore from the Congo, they cannot therefore satisfy the requirements of their customers. Thus the only safe option is to not buy from the Congo at all until it's all resolved.

The other option is to keep two supply chains going - the US acceptable supply chain (all the way from mined ore to products in consumers' hands), and one for countries not so restricted. Put simply, unless alternative sources were significantly more expensive, then no-one in the electronics industries wants that level of complexity and cost.

SImon Hobson

Isn't it obvious ?

>> What's the difference in having a SIM as part of the main board & one in a socket?

Apart from the fact that it instantly means Apple both control which networks you can connect to (even retrospectively changing this **after** you have bought the device) and knows which network you are using ? If Apple have a disagreement with a network, they can simply not put that network's keys into future devices - that means the network will effectively be forced to play to Apple's tune in everything it does which I cannot see as anything but a bad thing.

But wait, there's more. This doesn't just apply to new devices, since you will have to get Apple's blessing to switch networks, Apple can disable the ability to switch to any network it doesn't like for devices it's sold in the past.

And as others have already pointed out, it stops you swapping SIMs at will - whether that's swapping SIMs in your iWotsit (such as when travelling), or swapping one SIM between your iWotsit and something else. On the latter, I have a 3G dongle which I occasionally use with my laptop - I don't have a separate SIM for it, I just borrow the one from my mobile.

Lastly, ever looked at mobile options ? Look at most operators an they have iPhone and normal options for SIM only tariffs. So you can pay more for a contract or PAYG SIM for an iPhone, or less for a generic SIM only deal. Once you can't put "any old SIM" into your iWotsit, then the operators can also ensure that you can't buy a cheap contract instead fo the more expensive one.

No, I see nothing good about this - not for users at least.

SImon Hobson

It's coming ...

Whilst many ISPs still have their heads in the sand, others are working on it. Plusnet are currently running a limited trial (only 20 people I believe) specifically to work out what works, what doesn't, and what needs to be addressed for it to "just work" with end users. I believe they already have core networking supporting it. Some of the users on the trial are reporting good results with standard routers - but as you might imagine, there are only a handful doing IPv6 at the moment.

At the moment IPv6 is work. Give it a few years and I think we'll start to see some adoption - and once the ISPs start supporting it, and the customers are using routers that support it, we'll find ourselves with a growing number of people using it without actually knowing it.

Yes we need to sort out firewall stuff, yes there will be hurdles along the way, but if we all start looking at it, and adopting it (even if only piecemeal) then it will come and it will get easier. The hardest thing is the change in mindset required.

@ Terry Maguire

>> We use the internet for B2B marketing and were shocked to find that we could be blacklisted without any warnings and only found out via our customers.

Ahh diddums.

Quite frankly, most "marketing" is spam. Apologies if you genuinely only ever send mail to those who genuinely and **knowingly** opted in - if you are then you are in a very very small minority. Note that failing to tick a box, hidden at the bottom of a long form, drawn in pale grey on a slightly paler grey background and labelled with pale grey text, does **NOT** constitute an opt in.

If you were prevented from sending emails because of being on a blacklist then the reason is that the recipients had made policy decisions that they don't want to receive mail from the sort of outfits that find themselves on the blacklist(s) they use. Once you realise that, then your complaint becomes "I couldn't send mail because the recipients didn't want it", and the logical extension of your comments becomes "people shouldn't be allowed to block our emails just because they don't want to receive them".

As an analogy, I'm sure some (for example) minicab outfits have policies about the types of people they want to have in their cars. Some may have a policy not to take bookings from the "rougher end of town" - if that is the case, then your complaint that they won't pick you up is down to you choosing the wrong place to live. The internet is a bit like that - if you make the mistake of setting up office in a rough neighbourhood (ie an ISP that supports spammers) then I'm afraid you'll just have to live with the fact that you won't be able to deal with the people who don't want to deal with email from "the rough end" of the internet.

That is a policy decision made by the people who set up their mail servers. The blacklists simply provide an opinion about any particular bit of the internet. They don't block any mail, and no-one is forced to use them if they don't want to.

I run the mail service for a small ISP/IT services company. Yes we occasionally get blacklisted, and it's almost always because one of our customers has been a d**khead with the stuff they send. However, I find dealing with blacklists a lot easier than dealing with the f***tards at the likes of AOL.

>> Of course such a vehicle would have the normal steering eccentricities of its parent - turns one way when accellerating, the other way when braking

Actually it wouldn't if the "outboard" wheel were driven as well as the inboard one. The reason a motorcycle and sidecar combination does what you describe is because it's one wheel drive - with the driven wheel offset from the centre of gravity (CoG). Make the drive match the relative positions of wheels and CoG and it would drive normally.

On the other hand, I;ve been wondering about the inclination of the sun, and whether there is any scope for improved orientation of the panels towards it. Probably not as the additional complexity (and weight) would probably be more of a hindrance than you'd gain.

SImon Hobson

What's the issue ?

It's possible to use something and hate it (or what it stands for) at the same time.

The argument goes like this :

One the one hand, you can dislike closed systems. If you are fanatical about it you can be Richard Stallman - and for the record, I believe he has a point.

On the other hand, most people need to get jobs done - or even just lead a life. So the pragmatic approach is that you use what you need to use in order to live/work/whatever, while also arguing against the bad elements (like the walled garden approach to IFondle devices).

So it's (IMO) not that big a deal to own an iPhone, but argue that the walled garden is bad. In fact I believe you are less likely to be dismissed as a nutjob (as Stallman often is for his hard line attitudes) if you are in a position to say "I use one, this is what's good about it, but this is what's bad about it and needs fixing".

>> Presumably the side of the earth that is facing away from the burst is OK initially.

But only for up to 12 hours ? I'd hazard a guess that these vents, while only being a 'blink' in cosmological timescales, could actually be of considerable length. We're talking some very massive bodies, that even at massive speed could take days, weeks ?, more ?, to finish their collisions.

So if the burst lasts more than a few hours, the earth will simply rotate in it, much like the meat pillar in a kebab shop, and we'll all get a nice uniform roasting.

>> Your bank or the police will never cold call you or email you and ask you for your login details, cards or PINs

So why do I get phone calls from my bank (I contacted them to check and complain) who expect me to prove who I am before they'll give any evidence who they are ? They started with wanting me to give them half of my postcode, and they'd give me the other half as confirmation - and lets face it, it's not hard for someone to get my postcode. I assume (but didn't get that far) that once they'd proved who they were then they'd start asking me for security information. I don't think so.

And lets not forget that Paypal keep emailing their users with a link to login through. All the effort most organisations go to persuading people not to click on links in emails, and PayPal ask users to do exactly that !

They always have been doing it

IME people have been doing this to some extent or other for years - in fact from before it was called business intelligence. The only change is the sophistication and scale that is possible with modern systems.

The key bit is not so much technical, but personal - do the people doing it understand what they are doing or what the data they are analysing actually represents.

Again, my experience is that savvy managers will request the "IT people" to create them a report, and then they can extract the data they want and import it into Excel (or whatever) with a few clicks. This is one area where systems have improved - it generally being easier to get at your data than it used to be.

Doubt it

The same laws would apply - if Sky have sold the rights to publicly show their logo etc in Greece, then it is illegal for them to restrict the transfer of those "goods or services" within the EU. That's exactly the same argument the premier league used - they'd only authorised the showing of their copyright material in Greece via that provider, and so argued that showing it in the UK was a breach of copyright.

Err, yes you can !

>> I just purchased Star Wars Complete Saga on BluRay and my Samsung BD-5300 BluRay player can no longer read the disks so I have an $86 set of disks that cannot be returned since i opened them to play them and a BluRay player that is rendered "unfit for the intended purpose" by DRM.

Well if the disks are faulty then you CAN return them (I assume you are in the UK ?). Any statement that you can't return them because you've opened them is in conflict with your legal rights and therefore null and void. If they are sold as BlueRay discs, and won't play in your BlueRay player, then one or both is not fit for purpose and your rights under the Sales of Goods Act and Sales of Goods and Services Act come to your rescue.

Between them, they state that it is an implied term of any contract between a consumer and business that the goods are as described, fit for purpose, and reasonably durable. If a BR player won't play a BR disc then one or both is "not fit for purpose" - though your difficulty is determining which if you don't have another player to try the discs in. Of course, if you ask at the time of disk purchase if it will play in "<model X> BR player" then they will say yes - if they don't then the "fit for purpose stated at the time of purchase" bit kicks in and it's the disk retailers problem even if the incompatibility os the fault of the player.

But if your player plays other disks, then you can infer that it's the discs and return them to the retailer. IMO it is ones duty to do so - unless people stand up and pass the cost and inconvenience back up the chain then there isn't any disincentive for the vendors to keep heaping up the midden. If they find it's costing them hard cash then they may, just, start to think again.

What would be ideal would be for enough people to take discs back that a major chain (such as ASDA or Tesco) threatened to drop the output from a manufacturer on the grounds that the returns were too high. That is what it will take for anything to change. One can but dream !

Don't leave it at that !

>> I got an iPad a year and 2 months ago

>> The ensuing hubris was surprising in this day and age. £200 for a refurbished replacement with 90 day warranty. Pay up or f*ck off.

If this was in the UK, then go back and demand a repair for a faulty product. The manufacturers warranty is completely irrelevant - you have LEGAL RIGHTS which no vendor can take away from you. Note that your claim is against the retailer that sold it to you if you didn't buy it direct from Apple.

The key words are "not reasonably durable", and the fact that this comes up as a known problem supports the view that this is a design/manufacturing defect. Note that the law does *NOT* set any upper limit, but effectively it is 6 years in the UK as that is the limit for bringing any action in this sort of case.

Look up The Sale of Goods Act 1979 and the Supply of Goods and Services Act 1982

Once you know your rights, then I suggest you go back to Apple (or whoever you bought it from) and politely request a repair for this obvious manufacture/design defect. If they aren't accommodating, then point out that the above acts impose an implied term that the goods are fit for purpose and reasonably durable. 14 months for a "premium price" is not a reasonable life and therefore it has not proved to be "reasonably durable".

If they still won't play, then I suggest you get out the forms which you downloaded beforehand and start filling in their details. This is pretty well guaranteed to get the matter escalated and will probably result in a "goodwill" repair.

Whether you choose to go to the next level is up to you. Your legal rights are to have your iPad repaired (or replaced if repair isn't possible) and to claim the cost off the retailer. Any retailer with two brain cells to rub together will know that it will cost them more to defend such an action even if you lose (they won't get their costs back) and will not let it reach court. Apple in particular would not want such a case to happen - the bad PR would hurt when they claimed that an ipad is only good for 14 months or less !

Businesses only get away with s**t like this because too few people know their rights.

@ AC

>> MS aren't stupid, they realise that there is a massive market in running their older OSes on new hardware ...

Which is a big incentive for making Windows8 hardware requirements such that it won't run older versions. They'll have learned from the Vista debacle that they'll need to make it so users can't "downgrade" once they've bought a Windows 8 machine.

@ Tom 15

>> Surely people should be arguing with mobo manufacturers, not Microsoft.

No, it's Microsoft that are going to FORCE hardware vendors to include secure boot. Without this pressure, they'd probably not bother and we'd not have to worry. But having been forced to put the feature in. most of them will consider it a case "runs Windows, job done" and leave it at that.

It is true that we need to put presure on teh hardware vendors not to leave it at that, but it's Micro$oft that are driving this.

@ Field Commander A9

>> Users are always in control: if you don't like a locked down computer, just don't buy it!

Have you been living on another planet for the last decade ? Your attitude suggests the hardware vendors will care if we buy their kit or not - any threatened boycott will get the response "fine, we'll still be selling to the other 99.9% of people who don't care."

There's already a precedent for this. In the display card market, MSs requirements (driven by the big film studios) for video cards are to have a secure channel - locking down more and more into closed silicon and where certain technical details are NOT ALLOWED to be distributed. The result is fewer options for video cards, and less "open source" support for what there is.

The manufacturers really don't care if a few people don't like what they sell - their primary market is Windows machines. The result is that for advanced graphics on non-Windows is nVidia with their closed binary drivers, or ... err I think that's it.

David Austin has the best idea - the forum needs to make certain open features (ability to turn off secure boot, ability to upload additional keys) a mandatory part of the spec - that is the *ONLY* way to avoid this being a bad thing.

Thumb Up

Before my time ...

But I used to be in business with a chap who still used to use "Winchester" when referring to hard disks.

I still recall the "big step forward" when personal computers gained the option of internal hard disks. And of course, the excitement when the price dropped to a milestone £1/MByte.

Ah, nostalgia isn't what it used to be ! I'm with the others, more of this sort of article please.

SImon Hobson

Err ?

>> This Free software lets you define your own XHTML based forms:

What the guy isn't asking for is some software that lets him create forms (of any type). What he's asking for are **standards** so that the businesses he deals with can easily create structured documents **in a common format** which he can then drop into his own accounts software (which will read them as standard with them being a common and well used standard) and save the rekeying.

EDI was supposed to do that, but grew into some horrible mess of multiple incompatible file formats, but most importantly more or less requires complex (=expensive) software and services in order to shunt documents about.

SImon Hobson

It's a pity ...

that certain financial institutions don't heed common advice ! Yes PayPal, I'm looking at you (though others do it too).

PayPal are constantly sending out emails of the "have you checked your online activities lately, click here to login" style. Yes they are genuine, and they excuse themsleves by saying "you can tell it's genuine because we've included your full name".

I've had similar from a bank, and another bank is quite happy to phone me up and expect me to prove who I am !

SImon Hobson

Didn't stop if being 'sold' like that though

>> HD Ready has only ever meant that sets can display an HD picture via a suitable input; it has never meant that people could receive HD broadcasts

But that subtle distinction was never explained to most people - so yes, there are a lot of people who thought they were buying TVs capable of showing Freeview HD because the sale-droids were more happy taking the commission than putting them right. That, of course, assumed the sales droids even knew themselves.

SImon Hobson

Err ...

>> The power company can't force you to give them control over it.

Wrong.

If they come along and tell you they are going to change the meter, your choices are to :

a) let them

b) let them disconnect you from the supply

And someone else questioned the ability to remotely turn off supplies. It is my understanding that this is one of the key parts of many smart meters, so whilst it may not be mentioned, there's a good chance it will be there.

When you hear of large companies getting huge fines for their poor customer service, and the legendary billing cock-ups, the bet shouldn't be on whether there's an erroneous disconnection but when.

SImon Hobson

Like this ...

>> The faked certificates allowed websites to pretend to be authentic? Does anyone know how these were actually used?

I can't say how they *were* used, only how they *could* be used.

Without SSL, anyone who controls the digital path between your computer and another site can intercept the connection and pretend to be the other site. Having done this, the options are quite varied - they could forward all the traffic so the site still works but they can read it all in transit , or they could completely replace some or all of the information (ie feed you false pages). This si the basis of a Man In The Middle (MITM) attack - you sit in between two communicating parties and spy on or even alter the messages being passed.

SSL is supposed to stop this, because your client software (browser, email program, whatever) and the site negotiate a secure connection and your end can verify the credentials by following the cryptographic chain back to a root certificate. The MITM attacker won't have a valid certificate, and your client software can then flag up the "there's something wrong with the security" alerts.

But, if you've managed to get a fake but valid SSL certificate, then when you do your MITM attack, you do have a valid certificate, and so the end user never gets any alerts. This means if you are a government intent of suppressing dissent, you can eavesdrop on (in this case, it seems emails) that your citizens think are secure (the service is off-shore in a country hostile to your government, and the traffic is protected in transit by SSL).

Obviously, if you are planning an uprising and think your communications channel is secure, then you are likely to divulge details that would be useful to those that you are planning to rise up against.

SImon Hobson

Pah, you youngsters

I remember paying £320 for 2off 1MB SIMMs - and that was second hand and considered good value for the time !

Because MACs can't be faked, right ?

Once upon a time ...

There was this "rebel" OS called <x>, initially gaining use amongst "geeks" and scoffed at by business. But it's use grew and it became more popular, and business started to adopt it. But the various businesses supporting and selling it all wanted to differentiate "their" version, and so the different versions diverged. This was bad for users as it meant they couldn't but "Program <y> for <x>" but had to hope that the vendor of <y> had done a version for the variety of <x> the customer ran.

This forking and incompatibility held back adoption of <x>, and eventually it was sidelines as <z> came along and offered "one OS for everything". <z> became all embracing, crushing competition by lock-in and powerful marketing.

First time around x=Unix and z=Microsoft. Now is history repeating with x=Linux and z=Apple ?

SImon Hobson

Err, don't forget ...

This is the same OfCon that still won't accept that PLTs cause any problems worth investigating. The same OfCon that kept claiming they had seen no evidence of a problem a full years after it turned out they had a report in their hands that effectively said "massive problem".

This is the same OfCon that will quite happily sell the same spectrum twice. This spectrum already "belongs" to someone - you can be quite sure ofCon will extract licence fees from others to use it as well.

SImon Hobson

So do I ...

without paying anyone for a "service" to do it or having to contend with whatever clunky interface some vendor wants to inflict on you.

Recipe: Take one installation of MythTV, add as many networked frontends as you want (watch any recording on any TV), add recording rules to taste. Allow programs to record, then sit back and enjoy.

Of course it doesn't help if a program is never repeated for you to record ...

SImon Hobson

You have to remember ...

Firstly, Apple is now about selling you content - that means over the internet via iTunes. Thus it makes perfect sense to drop that dastardly optical drive that makes it easy for people to buy their films etc on disks that they can use as often as they want for as long as they want. What rotters, people shouldn't be shafting Apple like that ;-)

But also, on these machines there is a boot option (from memory, I've only fiddled with a Mini Server once and that was a while ago) to boot from a disk in the optical drive of another computer on the network. And also to use said drive later as well.

Oh yes, and if you don't have an optical drive - people can't complain that it's not BlueRay :-/

RE: So what innovation is really being killed by patents?

>> I reckon quite a lot but you don't generally get to hear about most of it.

The problem now is that patents are largely a tool owned and used by big businesses. They amass **HUGE** quantities of them, and keep patenting every more varied derivations from the same basics - as well as new areas.

The problems are many fold :

1) They no longer work as intended. Many patents are so "wooly" as to be virtually useless in actually understanding what's going on - and so society isn't actually benefitting from publication as was intended.

2) Because of the sheer number and breadth of scope, it is impossible to do a full search and find all patents that may, or may not, apply to your new widget.

3) Because of 2, it is now almost impossible to make anything that doesn't infringe on someone's patent. Your only way of knowing is to see how many letters arrive accusing you of infringement.

4) The system is broken. When the letters do arrive, unless you are also a big business, with your own arsenal of patents, then you have just two options - shut up or pay up. In effect, it matters not whether you actually infringe on someone's patent, it will cost more than a small business can afford to go to court and win. If you do win, you will still be out of pocket as you won't get your legal bills paid by the other side - perhaps in part, not in full.

5) The system is broken. If someone does infringe on your patent, unless you are a big business (note the pattern here ?), then it's unlikely you'll be able to afford to defend it. In effect, a big business can just take your invention, steal it, and screw you in court until you run out of money and fold. It's happened time and time again.

The original idea behind patents was that in return for publishing details of your invention, and so enriching scientific knowledge in general, you got a limited time in which you could prevent anyone else using it without a licence from you. So if you came up with a great new idea, you could share it (society benefits) and you could also still benefit from it. This was seen as a win-win situation as it genuinely encouraged innovation as you actually had a chance to benefit before others just copied you.

Now it's stifling innovation. It's a brave inventor that tried to get anywhere now without backing from a big business. If you do come up with something genuinely new then it's expensive to get a patent and even prohibitively expensive to actually use it. Meanwhile, those same big businesses will almost certainly find a patent they can accuse you of infringing, and so can effectively shut you down - even you aren't at fault.

That brings us to the argument in the article - that Google was stupid not to buy Nortel's patents when it could have done. These days, as explained above, business is done like the cold war - you need to have enough weapons (patents) to shut down the opposition so that they'll be too scared to use their's against you. That was a big problem for Apple when it started making phones - people like Nokia have so many relevant patents that Apple could not avoid infringing on them, and not having anything to fight back with, Nokia (and others) could effectively name their price.

So the current patent system, especially in the US, is broken. The period of protection is too long. Patents are awarded too easily. It's too costly for small guys to get a patent. It's too costly for a small guy to enforce one. It's too expensive for a small guy to defend against an infringement charge.

SImon Hobson

unlikely

>> ... lawers will split into into a change per infringement so say they've found 1,000 mp3 tracks on your hardware which look suspect then of course you can appeal but that's 1,000 infringements.... cost to yourself of £20,000 ...

But it's going to cost them a lot more than £20 per charge to submit the charges - so they aren't going to spend upwards of £100k or more unless they really, really, REALLY think they'll not get kicked out of court by a judge (or out of the tribunal by the panel). And talking of being kicked out of court by the judge (or out of the tribunal by the panel), I suspect a stunt like throwing 1000 separate charges would be thrown out as an abuse of procedure.

All in all, I think that bit seems proportionate.

What really irks is that the "you can steal copyright by a lame search intended not to find the true owner" measured that have resurfaced. As the article points out, that will fail again as too many people will be against it, AND I wouldn't be surprised if it didn't conflict with the Berne Convention.

SImon Hobson

And for those interested ...

RadCom (the journal of the Radio Society of GB) has been running a series of articles about a number of different amateurs who've been experimenting with long range transmission by light. By carefully focussing both transmitter and receiver with lenses they've got up to some quite impressive distances - which is actually not easy in this country as it needs very careful choice of locations to get a long line of sight.

But as said, it's not new. Didn't heliographs go back to ancient greek times ?
