UK ministers' Broadband '2.0' report confuses superfast with 10Mbps

Dave Bell

Re: Don't shoot/kill the messenger...

It's different sorts of cable, and that matters a lot.

There's also some pretty horrible wiring, network and power and telephone, in some buildings. The old BT telephone wiring was done decently, though I know of one house that had the line running through an orchard, not even clear of the trees.

The old telephone systems were not even made for data, and I remember some very geeky arguments about the difference between Baud and bits-per-second.

Re: Available but not realistic

"Line of sight" on these links may be a little less critical than you think.

For an example, a FiberNinja video on YouTube: https://youtu.be/DGOPESpU64A

Though it's not that long a distance, which would help.

Another report by ignorant people.

These people have been hopelessly confused by the advertising use of "fibre", a label defined in a way that would have included my first 300 baud dial-up modem, because the signal was only on copper for a few hundred yards.

They also ignore measures such as bandwidth per person.

Re: Alternate

There are other choices, but who do you trust?

If I were suggesting a non-ISP address for DNS, I would try to identify the server in human terms as well. Even on The Register one should assume one is being read by humans.

I infer the suggested fix doesn't care which server is used. In my case I would be working through my ADSL modem/router which provides NAT and DNS for the LAN. In turn, it can either automatically use the ISP server, or an explicitly set server such as the Google one at 8.8.8.8

Judge uses 1st Amendment on Pokemon Go park ban. It's super effective!

Dave Bell

Of course this is still current

There was a Pokemon GO event organised in Chicago this weekend, huge crowds and a lot of technical things went wrong. That was a big formal event, and would fit with the sort of big event this law seemed to be based on. A lot depends on the scale.

If was big enough that one of the problems was the local mobile network was overwhelmed. That seems to be the sort of level where the freedom of speech of the event is messing up the freedom of speech of other people. I know large events in the UK will set up portable base stations for mobile calls.

I suppose the next few weeks will be the test. School holidays.

There have been new Pokemon appearing and changes to both the gameplay and the key locations.

tl:dr The game can still attract crowds which can mess up mobile phone networks, as well as the obvious problems of litter and general safety

Ten new tech terms I learnt this summer: Do you know them all?

Dave Bell

Re: Teledildonics

The first times I saw it, it was in association with multi-player text-based games, and some of those are still running. There were already comments about one-handed typing taking place, and it's still arguable that it's more fun to create personal text, rather than rely on something that looks like just another porn movie. A lot of the VR erotica turns out to depend on motion-capture animations.

But even with just text, and a dial-up modem, these remotely-controlled devices could be added without using excessive bandwidth.

It may have all the problems of the Internet of Things, and it's simple enough that's surprising that it's still so obscure. Some sort of simple motor control may be all that's needed. But add a bit of security, IP67 sealing (a QI charger would be good), and developing a safe and secure control app, and I rather doubt the numbers would work out.

Do you really want hackers to take over the teledildonics? There's likely a kink for that. Rule 34 applies.

Openreach asks UK what it thinks about 10 million 'full fibre' connections

Dave Bell

Re: Why?

I don't see any reason why there has to be a single choice of ratios. If I could trade a bit of download capacity for extra upload bandwidth, I'd be tempted.

The current situation is like expecting everybody to drive an 850cc Mini. It could do a lot, more than you think, but sometimes I needed a Land Rover.

When there is only one product, maybe with a bit of badge engineering, do you really have a market?

Any download can saturate a connection while it is running, and one advantage of bittorrent is that is doesn't put all the load on one server. I used if for my last Linux upgrade. That tech has had options to limit download rates for years, and just being able to do that, not saturating the physical connection, would make a big difference. Why not run the download overnight? How many different huge files do you need to download now?

I get enough from ADSL for video streaming and gaming, but I am living alone. When my brother visits, we have to be careful. There are some things emerging which would need more bandwidth than ADSL can provide, but whether they are even usable from the UK, because of the effects of ping time, I am not sure.

The current fibre to the cabinet option is expensive, and I just cannot get reliable info on how much more bandwidth I would gain. If Openreach want people to buy into this, they're going to have to reach out and be more open.

Now here's a novel idea: Digitising Victorian-era stamp duty machines

Dave Bell

Not sure if it was stamp duty

Yes, it happened. I'm not sure it was quite the same thing as Stamp Duty, as it was a fixed fee for the document, rather than a percentage of the transaction. So the tax-stamp was already on printed cheques and the money collected as part of the per-cheque bank charges. But you could still write out the whole cheque on any piece of paper and add the stamp.

That was already unusual in my father's day. He was given a cheque like that when he sold a farm trailer, written on a sugar bag that had been re-used to wrap sandwiches. He was a bit worried, he told me, but the people at the local cattle market knew of the guy. and the cheque went through clearing.

I am not sure what the current system would do. A cheque could also be "endorsed": it was an instruction for the bank to pay you. and you could add an instruction to pay somebody else. My father said that some of his cheques went through a chain of several endorsements at the cattle markets such as Melton Mowbray, Uttoxeter, and Bakewell. It meant that people trusted him.

Maybe that's the sort of business dealing that inspired the idea of blockchain currencies. I doubt anyone involved in that has the trust that my father had. It's a hard act to follow.

GSM gateway ban U-turn casts doubt on 8-year prosecution in Blighty

Dave Bell

It's at least arguable that there have been technical changes of the lifespan of this law.

Meanwhile, it is hard, from round-trip times, to figure out whether an IP address is in the UK or not. It may be that everything goes via a few nodes, such as Telehouse, in London. Or it may be that everything goes through a few nodes in Cheltenham.

The CPS might be close to honest, but can we trust their political lords and masters.

Good luck building a VR PC: Ethereum miners are buying all the GPUs

Dave Bell

Other problems for VR

The graphics hardware, computer and display device, are looking to be a big barrier, but some VR concepts also seem to depend on fast internet connections, not just bandwidth but round-trip-times to servers. I have seen a figure of 40ms quoted before there start to be problems with people sharing an environment, but it hasn't been clear whether that includes the transmission time across the internet.

Maybe it's enough to wait for the 3D world model to download, and then a user can walk around the new building to see what it looks like, but as soon as you have somebody else in view, not in the next office, there will be problems.

You can cope with these problems with a monitor screen as a window on a virtual world. It's the new VR element, the head mounted display feeding each eye and overwhelming the other senses, which make any sluggishness a problem.

40ms? That's barely big enough to cover California. Bandwidth has increased enormously, but the round-trip times have hardly changed since I started using dial-up.

And I have not seen a convincing explanation of why I might be wrong. But it looks from here as if the VR-hype comes from a geographically localised cluster of enthusiasts around San Francisco Bay.

BOFH: That's right. Turn it off. Turn it on

Dave Bell

Re: Not scary - true

That's a perilous path. A bug fix, making something work as documented, is one thing. But if the fix is done by somebody who hasn't checked the documentation, and changes the name of some menu option on the way, is the sort of thing that turns a BOFH into a mere user.

Over the years, I have seen a lot of art that only looks good on a badly adjusted monitor. Most people can't even get brightness and contract right, though you may have trouble getting the full range.

I used to do this with chemical photography, and printing an image has all the same problems. You cannot get anything whiter than the paper. The BOFH obviously knows this. 8 bits on the data, and 6 useful bits from the monitor.

Those high range images do have some use, but most of the detail will get thrown away at the end. And not even Ansel Adams could give 8 stops brightness range. (Different jargon, 1 stop difference is a factor of two, 1 bit.)

Feelin' safe and snug on Linux while the Windows world burns? Stop that

Dave Bell

It's about control

I run Mint Linux, and v18.2 has just come out. It's based on the most recent Ubuntu LTS version.

There were a couple of big changes, but if I used the update process, I had the choice whether or not to use them. Do I switch the window manager? Do have make the jump from the 4.4 kernel to the 4.8 kernel?

Or I could install from scratch.

I used the update process, and then made the optional switches. It was all under my control.

I like being in control.

London suffers from 'sub-standard' connectivity - report

Dave Bell

What do these surveys measure?

I have my doubts about some of these surveys.

I have been on ADSL since it was introduced in summer 2005. The speed has increased a couple of times, a change in contract details (it was throttled at first) and then a tech improvement. It's OK as a speed for a single user, and I don't feel any urge to go to FTTC. I may be moving before next summer anyway.

This whole "up to" speed advertising thing is an illusion, but some of the surveys I have seen seem a bit vague about how they compare fibre and ADSL. Also, I think my connection would be in the "up to 17Mbs" category, and that would drag down the averages even if, from distance to the exchange and the like, I would reckon my speed pretty good.

It does sounds as if there are genuine reasons to complain about the situation in London, but the way some of this is being reported is hiding the way in which many people may be deciding that there is no point in paying for the higher speeds.

What? What? Which? Former broadband minister Ed Vaizey dismisses report

Dave Bell

It's more than just download speed

I get an adequate speed from ADSL, but upload speed is terrible, and if I was sharing a connection with a family, several people wanting to do different things, it wouldn't be enough. Some things, like VR headsets, are claimed to need low ping times to work well, and the UK's backbone network probably fails that test: everywhere seems to be abour 50ms from everywhere else in the UK.

That last problem may be why researchers are seeing people staring at the centre of a VR display, staying concentrated on the straight-ahead view. Is it bad design of VR, or is it that the slow ping times deter head movement by inducing motion sickness?

This might be why one long-established VR company keeps deferring the launch of a new product and keeps hyping it with a touring show. They can't get low enough ping times. The ping times I get today are rarely any better than I got with dial-up a quarter-century ago.

Re: Rule #1

For how long can I trust Google?

I have a little notebook with a list of DNS servers, including my ISP, Google, and OpenDNS. If something did go pear-shaped I don't need to look them up on the internet,

Worst-case, I have my android phone.

Doesn't solve the who-to-trust problem, and the whole connection could still fail, but it's some extra resilience.

I actually was with Talk-Talk for a while, after a take-over. Since I have my own domain-name and use non-ISP email, all they had to do was move packets, and they were OK at that.

Some of this is a habit I started in my dial-up days, when the company was bought by another (and both have since vanished).

Only downside? My weird interests can be tracked a long way back, but some of them are even in print.

Re: But.... Does it actually work?

It's nothing like flat earth, but GPS does make assumptions about the shape of the planet which makes slight differences to the latitude and longitude readings.

The basic differential GPS idea will cover things such as that, but it means the ship will have to transmit some sort of signal. This doesn't need to be powerful, but there is no way around a transmission from ship to returning plane, just to get into visual range.

Most GPS error comes from variations of signal velocity in the atmosphere, and there is always going to be the "cocked-hat" known to old-style navigators. As an extra problem, a ship's deck is never going to be as stable as a concrete runway. With the ship moving, it can't be quite like the differential GPS sending an error signal that can be applied in the vicinity of a fixed location. What the ship would have to do would be to transmit its current GPS position, encrypted, and the incoming plane gets a very good relative position.

Nvidia: Pssst... farmers. Need to get some weeds whacked?

Dave Bell

Nothing really new here.

I was seeing this general sort of selective herbicide technology in the sixties. It wasn't just herbicides that affected weeds but not the crop, but for certain sorts of crop it was already to cultivate to kill weeds between the crop rows, and it was trivial to use the same control system for a herbicide spray. It was called band-spraying.

I remember seeing ways of pulsing the spray on and off to hit non-crop plants at an early LAMMA show. I think that was when the show was at Lincoln, and that would put it in the last century, but I can't find the date when it moved to the Newark showground.

One of the problems that might have been solved is how the whole system behaves. You need some way of producing a cloud of liquid particles, usually a mix of water (as carrier) and pesticide, that are the right size particles to stick to the plant, not bounce off, when they hit, and large enough not to be too easily affected by wind, or evaporate too rapidly. There may be adjuvants, such as wetting agents. And somehow with the rapidly varying flow, you need to keep the pressure right, if you're using a hydraulic nozzle.

There are other ways of generating the droplets. with more control over droplet size, but I am not sure they can be used to aim the droplets.

This is starting to look like somebody having a clever idea about image recognition, which is good, who know sweet F.A. about actual farming.

We were in at the beginning of the Green Revolution, and I was coming home from school and doing things as routine that my teachers had been telling me were impossible.

At least my teachers knew about crop rotations. They did get confused about Jethro Tull.

The revolution will not be televised: How Lucas modernised audio in film

Dave Bell

Re: Also Sound / Video tests.

The argument is that low-frequency sound from a sub-woofer is not very directional, the wavelength and the size of our heads, but when I set up my system for Fellowship of the Ring I had a pair of stereo speakers which were rated for a lower frequency-response than any sub-woofer I have seen. Nothing that special, just big speakers. If you have the TV set up in the middle of of a good stereo pair, you might not need the centre channel. It was the rear surround that really made the difference.

You don't need huge speakers, but a box about the size of four hardback books is a good balance. A lot of computer speakers today are just too small, about on par with the old transistor radio.

I worked in a noisy environment, and I probably can't hear the difference that a tweeter would make, but some pre-packed sound systems look to be all-tweeter.

Netgear 'fixes' router by adding phone-home features that record your IP and MAC address

Dave Bell

Re: Similar technical data

Some countries, you can get a decent Geo-IP fix from the RTT to known servers. There's a research project based on this that I took part in, and one of the possibilities is confirming a Tor-node is in the country it claims to be.

Trouble is, the UK seems to be wired, via BT, so that everywhere is the same distance from everywhere else. So every ISP's address block is in the same fuzzy 30ms block as everything else, and my RTT to servers in California is little different to what it was on the days of dial-up.

The results I got plotted a circle that was about the same radius as the distance from London to Timbuktu.

Wannacry: Everything you still need to know because there were so many unanswered Qs

Re: No place to hide

It would be a very bad idea for any government not to cooperate, though there are some good reasons not to hand people over to the USA for a trial. And we might not be much better But the scary prospect is for some government, absolutely sure of somebody's guilt, bypasses the legal process and arranges to push some hacker off the platform in front of a train.

Part of it is the thinking that we know, but cannot give away how we know.

This feeling that some governments are willing to mess around the system lies behind some aspects of the Julian Assange case. The people who worked on this malware may have killed somebody in the UK, and it might legally amount to manslaughter. They aren't innocents. But I would rather trust a court than a politician.

Britain shouldn't turn its back on EU drone regs, warns aerospace boffin

Dave Bell

Everything the EU did had to be made into British law by our politicians, and much the same for this, through the CAA. And issues like this should have been argued about before Mrs May even sent the "I quit" letter. Some of the problems are in the EU stage, others on the people, politicians and civil servants, in this country, but it's so convenient to blame the EU when you get something wrong.

I've seen it happen.

And people such as Boris Johnson lied to get the result they wanted, and the new PM rewarded them by giving them high office.

Labour are not that much better

They're all blaming the EU for the problems, and expect us to let them run the country. The EU doesn't have to be all that clever to look better than the British Parliament..

'Windows 10 destroyed our data!' Microsoft hauled into US court

Dave Bell

Re: About time

I had bought Windows update CDs in the past, a couple of times. No big problems. Then the hard drive needed replacing, I was able to save the data, but the hardware change meant I needed to go back to the start of the stack of CDs, install and register that version, install each upgrade, and then ask myself, "Windows 10?"

I installed Linux

Six weeks later, the company responsible for some software I used announced (with a notice in the back of their cellar, behind a locked door labelled "Beware of the Tiger") that the Linux version of the software was an unsupported beta.

I found other software that worked. Last I heard, they still were not officially supporting Windows 10 users. As for 64-bit code, they have started working on it.

Amazon dodges $1.5bn US tax bill: It's OK to run sales through Europe out of IRS reach – court

Dave Bell

Re: Other countries?

I think most of the treaties are bi-lateral: the UK has its own tax treaty with the USA.

The way Amazon handles Kindle book publishing means I have to see my money go through the USA and the US tax system., which does make this subsidiary in Luxembourg feel a bit fake.

And I know the EU is getting a bit active about the tax deals, such as VAT rates, that Luxembourg did.

I don't just what all this adds up to, but there's far more questionable behaviour by these big American businesses with subsidiaries in the EU and large fees being paid for IP rights so as to avoid tax, if not outright evade it. It makes this report seem a little inadequate.

(Of course, if the EU is leaning on some countries about how they have set tax rules, it's easy to imagine a motive for some people's attitude to Brexit.)

Europe will fine Twitter, Facebook, Google etc unless they rip up T&Cs

Dave Bell

Old laws, new internet.

There's been a lot of scary stuff in T&C lists, and at least some of it is about making the internet possible under copyright law. It has always been there, and sometimes the terms have been abusive.

The problem is that the internet depends on making copies of data, and the Berne Convention make the existence of copyright automatic. Part of it is a right to be identified as the creator.

At least the USA is signed up to the Berne Convention, but it's a minimum standard.

And that's why they want their non-exclusive licence to use your material. Just to make it visible to their other customers, there have to be copies.

Doing it in a way that would be clear in court is a bit tricky, but that problem has been as the root of a lot of arguments about the use of content. The scary part for me is that they rarely try to limit the licence to any particular service. It may be that they could be sued under bankruptcy law if Twitter went bust, and their T&C limited that use-licence just to Twitter, so that data had no value

This isn't entirely what the current argument about, though where you might sue an international company is a significant problem that the EU will care about. It comes with free trade. Likewise, where a company pays taxes.

It's another whole giant economy size can of worms that comes with deciding whose national rules apply to content.

At that time. some aspects of medicine, such as physiotherapy, seemed to be part social-services, part NHS. After my mother died, some of the support services moved from council employees to private companies.

One of them I was able to get CallerID on the call, which I was able to pass on to the cops.

They were all variations on "our servers are getting warning from your computer", leading up to expecting me to download software. I kept asking them if they had the IP address, or the MAC for the network interface and they kept insisting they had a Customer License ID that was "burned in" to my computer.

The first few times, I managed to keep them talking for a few minutes. The last time, they hung up as soon as I spoke. I wonder if they even know which phone number they are calling.

Facebook shopped BBC hacks to National Crime Agency over child abuse images probe

Dave Bell

There's a lot of room for argument over who to blame, but I think it's the cops who need to take a hand now. It's not just about whether the BBC should have reported to them, or whether Facebook should have called for sample images. Some of it seems to be context driven, such as a not-all-that-blatant pic of a schoolgirl attracting a flood of abusive comments. I am not sure the cops can set all that definite a line, but they're the one who have seen the pictures, not us.

At the end of the day, they might need to interview the people involved under caution, and ask to see the letters between Facebook and the BBC. We're not getting quite the same story from the two of them.

Both could have made mistakes in this.
