Nah - I'd do it for the props, not the money. There are other motivations than currency. Others may do it to avoid nuclear fallout from when General Trump has a hissy-fit and pushes the other red button on his desk (however likely that scenario may or may not be).

Re: Ben Hur Moment.......

> you are perfectly allowed to do any speed you wish under the limit provided that a) it's safe to do so and b) you are overtaking someone in the middle lane.

It is demonstrably not safe to be in the outside lane doing 22 while everyone else is doing 50 - so you most certainly won't be overtaking anyone, and no-one can undertake.

A long while ago a mate was stopped for driving too slowly. Turns out he was over the limit, too, and didn't have a full license (just a provisional), and basically a bit of a twat for those two reasons, but the original reason was because he was slow.

Apple's adoption of Qi signals the end of the wireless charging wars

Re: Race over? I doubt it

I doubt it, it's probably "just slightly different". Intel have longed to get into the handset (and base station) market which QC dominates - to the point of attempting a partnership with Apple to supply chips to at least one model of their iPhone (sadly not as well performing as the QC variant, perhaps because of missing IPR that helps QC with their performance in LTE).

Cars are all starting to be configurable with a wireless charging pocket/hole, which is infinitely preferable to fiddling with cables on entry & exit. If only their was better adoption of the screencasting-type connection to get (suitable) phone apps on the car display - e.g. your satnav of choice rather than the shite that is usually bundled with the car.

London Tube tracking trial may make commuting less miserable

Re: One thing I always failed to understand....

> The system looks at which SSID's your device is trying to connect to

No, no, no - RTFReport:

"When a mobile device such as a smartphone or tablet has WiFi enabled, it will search for a WiFi network to connect to. This involves the device sending out a probing request that contains an identifier specific to that device, known as a Media Access Control (MAC) address. If a WiFi network is

found that is known to the device, it will automatically connect. If the device finds unknown networks, it lists these in the device settings so the user can decide which, if any, to connect to.

During the pilot, if a device was near one of the 1,070 WiFi access points in the designated area, and it had WiFi enabled, we would have collected the request(s) to connect, even if the device did not subsequently do so."

Every mobile with WiFi enabled transiting through TfL's system will be probing their APs, even if they don't register. This leaves a MAC address record in the AP, which is harvested with a timestamp. This happens in shopping malls and airports (at least) for footfall analysis and is a fairly standard feature in the boxes. TfL have merely put the information together from their many APs in a useful way.

Last year TfL held a hackathon and exposed a wide variety of data feeds to the entrants (traffic light timings, road status information, traffic queues, ...). For all their flaws, they're being quite good at attempting to find ways to embetter their service offering.

Facepalm

arse, hadn't appreciated that if could be a composite of primes greater than your biggest prime in your set - case in point is {2,3,5,7,11,13}, which would result in 30031 when you use the multiply and +1 method, and 30031 = 59 * 509.

Perhaps I will graciously let them off and concur that what they are doing is really hard :)

I quite agree, but I don't think you need to go that far to get to a set that, when multiplied together, has more than 22 billion digits - if fag packet calcs are moderately accurate, the first few billion primes should do the trick and there's at least one website with over 37 billion in a list (that I think claims to be complete)

Well, you can make massive jumps quite easily, but slowly incrementing is possibly harder, particularly as this seems to be looking for Generalised Fermat primes, rather than just a regular prime.

I'd have thought it would be relatively easy to beat this number as the "largest prime" given a sufficiently large and complete set of primes. If the current largest prime has 22+ billion digits to it, then you just collect a sufficiently large set of primes, multiply them all together and subtract 1 - bingo.

I suspect it may be more complicated than this, though... :(

This can bork a Mac attempting to connect to a subsequent wifi network later on unless that DNS is explicitly linked to the domestic wifi AP. After my ISP's DNS fell over, I updated my home machines.

Later on, we had to take eldest rug-rat to hospital. The local hospital wifi does a redirect to an internal address to insist you accept the T&Cs before letting you loose on the internet - if you have a DNS specified on a Mac, the redirect fails/is blocked, and you cannot get on to the system. First you need to delete the custom DNS (or I think you can associate one with a specific "location", but I'm a Windows user, not a Macophile).

...I wonder what actual evidence exists to make the case.

Possibly quite a lot. If imagine there's a system architecture document pointing to high level requirements, suitably decomposed into lower level requirements for use by individual teams. As they code, there will be code reviews and modifications, plus development of tests (unit and system) to ensure it works as planned. Reviews of tests, gating documentation to ensure it has reached a commercially deployable state. All documented by project management and reported.

This is a German organisation, expect paperwork trails.

UK industry mouthpiece wants 'near-universal' broadband speeds of 30Mbps by 2020

JetSetJim
Silver badge

Re: Use cases please?

> That's my point, the vast majority of the country don't live in shared student digs, or have 4 teenagers at home. For them, a reliable 30Mbps will be more than adequate. Landlords of HMO student digs can pay extra for FTTP and flog it as an extra benefit.

640K was more than enough RAM for anyone (Bill Gates [1]) and there is a global market for, at most, 5 computers (Thomas Watson, IBM [2]), and there is certainly no reason for anyone to want a computer in the home (Ken Olsen, [3])

Currently, perhaps it is only the "premium" users who feel the need for more than wet-string between themselves and their local green box, but isn't that how the world works? People will find uses for it, and service offerings that use more bandwidth will become more affordable - even if it's just to watch ultra-HD cat videos. Kids are being brought up using devices that have more compute power in than was available to the whole planet 50-60 years ago (or some such number).

FTTP should be made to be the norm for *anything* new, and funds should somehow be made available (taxes / subsidy via subscription / ...?) so that non-fibre folks can upgrade.

I've seen a document showing that Openreach's new copper cables are in fact copper around a fibre core, so they've got that box ticked, and I'd guess that the copper could even provide a little bit of power to guarantee the ability to make a call in the event of a domestic power outage. All they need is to swap out DSL cabs with FTTP cabs (yes, they have lots of cabs, so it won't happen overnight, but then nor is their "superfast" FTTC upgrade rollout).

If BT don't do it, other folks like B4RN and Gigaclear will, and BT will lose customers, as will Openreach as they migrate onto competing fibre networks. Bye-bye BT, it was good to talk.

It would also be nice if s/w would notice that a file hadn't actually been changed before determining that it needs to synch it.

T-Mobile goes Apple/Google route by separating phone numbers and devices

JetSetJim
Silver badge

Re: So innovative

It's not cloning, it's registering one or more devices to be notified of incoming calls and to be able to handle those calls. Those devices may well be on another service providers network, and have their own contracts.

1G was an awfully insecure system, as everything was readily interceptable by any device in the network - which is why that worked. The same technique would not work from 2G onwards. However SIP was invented to support VoIP calls, where a central server keeps a record of subscribers to a service, and attempts to notify all registered subscribers of events related to that service. In that way, multiple different devices, on multiple networks, can register to receive calls to an IP phone number, and the IP phone service provider will attempt to notify all subscribed devices and establish IP bearers (not voice circuits) to those devices that respond.

Google and Apple like it cos it moves the operators one step closer to being a dumb pipe, this is another attempt to put the brakes on that on T-Mo's part.

The app will need permission for the following:

a) access contacts - so that you can dial from your contacts, or add someone to them from the app

b) network access (wifi & mobile) - so that the call can progress over a data bearer on an available technology. They may abuse this by also bundling enhanced purchasing suggestions in informative sub-windows of the app

c) at a stretch, location, but this should really be looked after by the mobile network infrastructure

To offer a more complete solution, it may ask to be able to receive and send SMS/MMS, use the camera (particularly if video calls are supported), and store media files. Potentially, to guarantee access to 911 facilities, it may require the ability to make a phone call (via cellular).

Re: App versus battery

It's basically a SIP call - your number isn't really deactivated, as your IMSI will be used to track you as you move around the network - sounds like they just have a lookup table that routes voice calls to you via the SIP service that notifies all registered appliances that you have an incoming call. All that happens here is that a SIP paging message is transmitted to those end-points, and the mechanisms needed to instantiate bearers to a particular device are invoked as needed - e.g. same as for when you get a notification that you have an email on your phone - typically a push notification for services such as Google.

T-Mo may be the first mobile provider to offer it, but it's been around for a while - I can receive calls on several mobiles for all calls to my home number, and have done for 2 years - and I'm pretty confident that the feature was baked into SIP at least 15 years ago.

Re: Motorola tried the same thing with Apple

> It all gets a bit murky but IMHO, QC have a bit of a nerve trying to base their royalties on the price of the end product.

IANAL, but the phone industry boils down to:

Manufacturer A uses a chip in a phone that t can only convince punters to fork out a 10% margin for (i.e. costs £100 to make, including all costs of business operations, sale price of £110)

Manufacturer B can use the same chip to get a 40% margin for arguably the exact same product

Should the royalty rate for manufacturers A and B be the same absolute value (e.g. 2cents/phone) for a SEP, or should it be based on the value of the product being sold that contains the IPR? I'm sure there are very good arguments on both sides of this conundrum.

OTOH, Apple do have a bit of a history of ignoring IPR of others (or bullying their way through it), and abusing their own IPR (rounded corners et al.)

Re: Wow. Abusing patents.

"But [Apple's] main argument at the ITC will likely revolve around how the Qualcomm patents at issue are now effectively an industry standard and so should be treated differently."

Assuming these are Standards Essential Patents (SEP) then they need to be licensed in a FRAND way. This is the only way they have to be treated differently, but the key point is that to be able to sell a phone in today's markets, you have to implement those patents in that phone, and so a royalty is due. The fact that they are essential means that the royalty rate must be fair, reasonable and non-discriminatory, so Apple will no doubt need to demonstrate that the agreement that they signed several years ago isn't in line with FRAND principles.

Re: Motorola tried the same thing with Apple

Don't know as it's that cut and dried - from the article, QC and Apple have had an agreement for a quite a while and now Apple are saying that they don't like it so they're not going to pay it any more. Try doing that with other things (e.g. rent payments on a flat, which I appreciate is a completely different kettle of fish) and you get handed your arse.

QC may well be arguing "well, 5 years ago you thought the agreement was FRAND, so go suck lemons".

On the other hand, these are statements from mouthpieces, so who knows what is the Truth (TM) and what is FRAND (if indeed the patent in question is a SEP one, although that's quite likely)

Re: If Huawei agreed an payment plan with Ericson

> I bet the original inventors of these patents got a one-time bonus of €1000 or so

As a recipient of several of these, I can agree that the original inventors will get such sums. But at the same time they are drawing a salary and are tasked with investigating such things on behalf of a company, with the use of expensive company resources to do these investigations. In a lot of these patents, not necessarily all, it would be difficult for someone to actually come up with the idea, prove it worked, and then spend the time and effort needed to get it into a standard, as well as forking out the large sums of money required to pursue the patent in the first place.

Yes, some patentable things can be bashed together in a garden shed, but increasingly in many areas, it takes a large investment to some up with small incremental ideas that together form part of a larger whole. I'm not bitter in the slightest about my patent awards.

Sure, there are problems in the whole area of patent law, but I'm not sure being able to trade ownership rights is one of them.
