BT pushes ahead with plans to switch off telephone network

Re: Mobile as the emergency option?

"You do get location from a mobile - if it is using AML and requires certain phone OS's (need to have IOS 11.3, Android 9) at the moment. However, the control rooms also get a triangulation data from the mobile network masts (cells) your phone is registered on - this is accurate to 100m ellipse in built up areas but less in rural - depends on the density of mobile cells."

I've never had any indication from any emergency services operator that they have even the foggiest idea where I am from their control room.

And given that control rooms are not generally all that 'local' the operator still often doesn't have a clue until I go out to motorway* junctions and then navigate them from there...

I take the 'emergency services get your location with a massive handful of salt, at least in the UK...

(Whether M class, or just de facto motorway)

Re: Mobile as the emergency option?

>you don't get location information from mobile

Networks have always provided an area ID based on the cell the phone is connected to.

Area ID isn't a house though.

and given the response from the emergency services when I have phoned them from my mobile - they get absolutely no location data at all...

Re: Mobile as the emergency option?

Not really - you don't get location information from mobile.

And in the event of a power failure your plain phone will work just fine - your fancy VoIP phone, with it's reliance on a separate route, access point, switch...??? will not.

It's the raw material needed to build the plastic again.

The enzyme takes the long chains, and spits out individual links.

A non-binding vote on a major issue - which divided the country basically into two equal sixths...

The two thirds who either couldn't or didn't vote massively outweigh the voting population.

The voting population was very finely balanced on an issue that is fundamentally asymmetric:

- if we don't leave now we can leave in the future

- if we do leave now we can't 'unleave' later

Personally I think the vote was a mandate to wave a big stick at the EU with regard to negotiations, but not nearly strong enough to justify triggering article 50 on it's own.

Another referendum in a decade or so would indicate whether the additional stick of the 'country ready to leave' has been sufficient...

Re: re not such a big deal

“OTOH it's perfectly possible to have a choice of KDE/Gnome/Mate/XFCE/whatever at login time. Not, not install time or boot time, login. That's interchangeability.”

I used to use ion3 (tiling WM) as my main window manager, and fire up xnest to have xfce embedded in one of the tiles for the odd occasion when I needed it...

Re: Nothing wrong with a merger OS

Those with experience with Linux will quite rightly point out that a different window manager can completely change how a device works.

You need a bit more intelligence to get the application to handle having two faces (if appropriate) but having One OS and two window managers doesn’t seem like an inherently bad idea.

"But where, as here, the copying is verbatim, for an identical function and purpose, and there are no changes to the expressive content or message, a mere change in format (e.g., from desktop and laptop computers to smartphones and tablets) is insufficient as a matter of law to qualify as a transformative use," the appeals court's ruling stated today.

Uber breaks self-driving car record: First robo-ride to kill a pedestrian

John Robson
Silver badge

"UK official stopping distance at 30mph is 23m, if a small child runs out into the road 1m in front of my car then it may be my responsibility to avoid them but the laws of physics disagree."

It was your responsibility to see them at the side of the road, or to see that you couldn't guarantee that there was no-one there, and adjust your speed accordingly.

Thus changing the 23m stopping distance into something much more reasonable, and starting at a speed which is far less likely to kill said small child if you still fail to avoid the collision.

I stopped wearing a watch years ago (my phone was a more accurate and useful device) so I need something pretty useful to make me want anything on my wrist.

I had a pebble for a while, I liked the ease of glancing at notifications, but that also made them more intrusive (even when driving it was tempting to just twist the wrist a bit).

I have to look at them and consider them a solution without a problem for most cases (kind of neat HR monitor, but really???)

Six things I learned from using the iPad Pro for Real Work™

John Robson
Silver badge

"If you want to do "proper" work, you need Windows (I hate to say it), proper Windows"

Funny - that's one thing I avoid whenever I need to do actual work. Some people might want it, but I suggest that's familiarity rather than need.

Unix works just fine... At the moment I'm sat with a BSD derived box at my fingertips. Makes a rather good tool, and is my 'work' machine.

I also have some experience of using the iPad as a productivity tool - for a while we went 'computerless' at home, and my wife wrote a book on her iPad2, with an apple bluetooth keyboard. The iPad has now basically stopped being useful (used occasionally for things), but I still use that keyboard when I work whilst travelling, since a keyboard and iPad mini actually make a great little work device - fits far better on a train/plane table than a laptop ever does.

One of very few things I struggle to do on the iPad is to remotely control a PC UI... And frankly I'm not surprised... I do wish they'd allow a pointing device (heck even if it's an app on a companion iDevice).

(Amusingly computerless is autoscrewuped to computerises)

Re: Every 30 months?

No - I'd suggest that it is made up two general groups.

- Those who are in the 24 month upgrade cycle

- Those who wait after their contract ends before deciding what to do.

And even then it ignores the second hand market entirely...

I plan to upgrade my phone this year, whether I need to or not, because it will then pass down to my daughter. The phone she currently has is:

a) old enough that many useful apps (such as libby - which gives library access to both e- and audio- books) don't work.

b) starting to have the screen fail (glitching up on the RHS at various times)

But given that it is now 6-7 years old I think that's not unreasonable. It's had one replacement screen in that time.

Then my wife and I will be in sync - with one upgrade per year, alternating which kid gets an update as well. Scheduled phone life - 4 years, publicly visible 'upgrade cycle' 2 years...

So you're not dressing appropriately for the conditions?

Some issues which are resolved:

I prefer pay at pump myself (at which point pre-auth is sufficiently easy to make sense - particularly since the 'refund' doesn't then need the card a second time) - but fuel theft is no different to theft in other shops (except that ANPR makes it really easy to ID the culprit).

Re: Still looking for an electronic lock...

>> I think you answered your own requirement there - a garage door opener, something that has been around for a long time and does the job it's designed for. Of course, those are still seriously lacking in security, but it does what you need in a way that doesn't require an IoT device.

There is of course the slight issue that I'm replacing the door due to failure of said device - and the way in which I installed it wasn't particularly conducive to replacement (Oops)...

I am indeed looking for something that I can control via an RPi - as I said, no IoT connectivity wanted/needed. But I could of course access it over my own VPN.

I'd like to be able to open it on approach, particularly in the event of rain.

When the remote opener on the door used to work it was rather nice to ride straight in without having to get off the bike, open the house, go in and trigger the door opener before coming back out again.

About to replace the door with something slightly less automatic, but I'd still like to be able to get the door to open for me, particularly when the weather is inclement.

This is why one of the non-negotiable features of cars I get is a speed limiter. It's a function of the cruise control.

I do tend to find that when I haven't set it, I am still cruising along a road at exactly the speed limit...

> Not that all camera's are bad, mind. There are a couple of places near me where the camera is very much needed because of poor (well, terrible) junction design and road layout. You'd hope, though, that sooner or later they'd spend some money to correct the layout....

Yes - changing the layout is preferable...

There is no real reason to be cross about any speed cameras, it's generally trivial to actually obey the law.
