Boundaries Commission slammed over mega map dump

Dave Bell

A PDF isn't a bad format for a map, which will tell many people what they want to know. Which constituency am I in?

I am not at all sure if a map-base for a rural area will be suitable for a boundary in an urban area.

But if you want to study what the changes will do, you have to work with historical voting data, however that's organised. That's when you want the spreadsheet listing the wards in the new constituency, and which old constituency they came from. Or maybe the areas assigned to each polling station.

We're lucky. The people whom organise the elections in this country are remarkably honest. But I'm not sure if there are any journalists with the statistical skills to analyse the numbers. Some of them struggle with maps.

LOHAN to suck mighty thruster as it goes off, in a shed

Dave Bell

I remember, decades ago, my uncle pulling some fancy tricks with Jetex motors. Out of the box, these were a re-loadable end-burn solid fuel rocket. The fuse was held against the base of the fuel pellet.

What melted the casing was carving the pellet into a star cross-section, which greatly increased the burning surface.

End-burn: constant thrust, longest burn-time.

Hole up the middle: Thrust increases with time, reduced burn time

Star-section: High initial thrust, pretty colours when the casing melted, caught fire, and set the model on fire.

But if you want reliable ignition, you may need a hotter igniter, which generates sufficient hot gas to set alight the main charge. And that may need the attention of somebody with the correct licensing to make their own pyrotechnics.

MPs blast dole-office-online plans

Dave Bell

A lot of what might be called "support" has been privatised.

A good many jobs on offer are never seen by the DWP systems.

And their computer-based system has real trouble with pinning down where a job might be. I've seen them class jobs in Swansea as local to Scunthorpe. I can understand a confusion between where a company office might be and where the job is, but it's still bad design.

I don't think DWP really knows what is happening, or how to find out.

'Find My Car' iPhone app finds anyone’s car

Dave Bell

I've seen several different sorts of ticket used. Some are meant to be displayed on the car's windscreen while it's parked, which would rather put the kybosh in this idea. It depends on the ticket being provided at an entry barrier. But there's no reason why the ticket can't have a clearly visible number. We seem happy enough to use a 4-digit PIN for payment cards, though this would clearly need a longer number.

I don't think ticket printing is the fundamental problem. It's whether the overall system can link a ticket to a vehicle. Most of the car parks I know would struggle to do that, because the driver has to park, and walk to a ticket machine to collect the ticket.

Aussie Sex Party takes the whip to .xxx domains

Dave Bell

I would suppose that the lawyers have already been over this deal very carefully, so that it can't be read by a court as an attempt at blackmail. Compared to a trademark case, this doesn't look a bad deal, but neither strikes me as a good deal.

More transistors, Moore’s Law, less juice

Dave Bell

It's not quite simple, but I think we are suffering from programmers who haven't adequately coped with the changes in the technology.

Computers used to get more powerful by running at a higher speed. That hit some practical barriers, and the response was the multiple-core processor. You get some gain just from the OS running on one core and the program running on another, and that's easy to do.

I can point to software, written in the last three years, able to use a lot of CPU power, which is still stuck at that crude level of multi-core use. Luckily, a lot of the work the program does can be handled by the graphics hardware, but the performance seems biased in favour of a particular GPU manufacturer.

Add the way that it grabs all the RAM it can, and that there is no 64-bit version (that might be an advantage, since it limits the RAM it can grab), and you have an indication of how programmers are failing to exploit the increased hardware speed.

And my fancy multi-core desktop monster doesn't really improve things for writing this comment. I don't type any faster. OK, so it has a bigger screen and a better keyboard than my netbook, but the feeble CPU isn't the limit on what I do.

We have too many programmers producing badly-implemented usage of processing power. I'd far rather see some smart exploitation of the falling energy costs. I used to run an office on a 1 GB hard drive, with plenty of storage space to spare. Now a memory storage device that small is becoming a little hard to find. But is the energy cost of storage reducing in a useful way when a similar physical device can store 2 TB. "Laptop" drives, of course. It does seem that cheap laptops are where people are spending their money, these days, and they are hugely powerful computing machines. They are saving energy, but they don't do so much more on a battery charge. We don't type any faster.

I don't mind having these huge hard drives. But Parkinson's Law seems to trump all else about computing. With a touch of the Peter Principle.

Hey Commentards! [This title is optional]

The problem is that English is a moving target.

Considering what some teachers have tried to do to the language, that would seem to be an inevitable survival tactic.

Reader-generated threads

I'd be very wary of that. You could get the same result by using some sort of letter-column article, inviting a more wide-open thread use, but I'm really not sure how you could combine moderated comment threads on articles with fully reader-generated topics.

Go look at Making Light for how "Open Thread" creation can work. But I doubt you will get the poetry. Or the debate on serial commas.

UK.gov works on YET ANOTHER open-source push

Dave Bell

In-house skills

Open Source seems to be no different to proprietary is you don't have the skills in-house to manage the software use.

You have to trust somebody else, for instance, to ensure security.

There is a perception that access to the source code means that somebody could add a security loophole. Yet without that access by the supplier, you just push the vulnerability back a step, out of the hands of the supplier.

I've seen that happen: a piece of software which used some proprietary graphics code to handle JPEG files, in the form of a DLL. Somebody, who had access to the source to the DLL, put in some sort of spyware. When that came out, it killed the product. (The crook got caught doing other bad things, and the whole affair unravelled.)

I don't have the skill to check the source code. But if it's Open Source, there's somebody out there who can.

Maybe too much has been privatised to be able to check anything?

Amazon solves wait-at-home-for-deliveries problem

Amazon invents bookshop! Film at Eleven!

A great many businesses with a High Street presence allow "collect at store" as an option. It works really well if the item happens to be in stock at the local store.

Amazon seem to be trying to get around their lack of local stores. Maybe there's a chance for some business to start providing this sort of service for many different retailers.

Goodness, we could call it a Post Office!

US judge tells Levi's to take its Euro problems to Europe

Dave Bell

More than pathetic

The thing is, LS&Co don't seem to have bothered to explain to the Judge why, under the American laws, he even has jurisdiction. It's not about the merits of their complaint: they didn't bother to explain why a court in Europe couldn't be trusted to enforce the laws of Europe.

But some lawyers will have run up billable time over this.

Plods to get dot-uk takedown powers - without court order

Dave Bell

A solution for other reasons

A ,com mirror, or a ,eu mirror, would make sense as part of a general strategy of protecting against failures. You have back-up servers in another location, and you have back-up name servers and domains.

Oh, I can see the point about needing to protect against fast-happening crimes: imagine an event like the HP fondleslab sale being a fraud, You'd have a couple of days after taking the money to do a runner, before people got suspicious. But I can't see the system being able to react fast enough.

I think this is something dangerous (and the police have always had tame Magistrates who can be depended on to issue warrants in the "right" sort of case). It needs some pretty strong checks, with statutory backing.

Couple can sue service that monitored their net sex

Stolen Goods

I doubt the circumstances protect her from a stolen goods charge. In England, there are a few get-outs based on "open sale", but it doesn't sound as though they'd apply, even if the law was the same.

BBC crowdsourced mobile map: A bit quirky, but useful

Dave Bell

With local experience...

The maps locally are mostly white--nobody has used an an Android phone with the software--though the pattern along the local motorway looks consistent with my experience.

I know where the local transmitters are, as there is a cluster of transmitter masts, and the signal drop-outs are consistent with that being the site.

The patterns do suggest that people with Android phones don't live or work in rural England. I would guess that a lot of the blanks would be a green fill, depending on the landscape. But nobody goes to the middle of a field to check.

Poor IT could leave Brit troops hanging in Afghanistan

Dave Bell

Ammunition boxes.

There is a story that part of the problem was than the ammunition supply faltered, because the reserve ammunition boxes couldn't be opened without screwdrivers.

They'd been designed so that they could be smashed open with a rifle butt,

The extended formation didn't help in distributing ammunition.

Police kill mobile phone service to squelch protest

Dave Bell

The hidden threat.

OK, BART provide a cellphone service within their underground stations, for the benefit of customers, and people are saying they can shut it off whenever they wish.

What if somebody collapses? Do you try to use your cellphone, or do you try and find a fixed phone?

Maybe BART are lucky they don't have an ambulance-chasing lawyer calling on them?

(I know people in the UK who don't bother with a landline telephone. Maybe they get their internet through the cable-TV system.. Mr. Cameron, I hope your scheme will still allow emergency calls to be made through the mobile networks.)

Hackers claim to have cracked Norway mass-murderer's email

Dave Bell

ECHR and EU

The ECHR isn't part of the EU: it's one of several Europe-wide things which have come to heavily overlap the EU. We're one of the countries which set up the ECHR, before the EU (or EEC as it was) ever came into existence.

There's people who do seem to like mashing all these different things together. I'm not at all sure of their motives in doing so, but blaming the ECHR on the EU is one of their usual lies.

Dave Bell

Intelligence?

That is more of an intelligence issue, though it may make it more difficult to get a warrant against somebody identified through these email accounts. Somehow, I doubt it. A reasonable cause to look for evidence doesn't have to be evidence itself. (Though the way some types of crime are investigated does justify a more rigorous standard.)

Any way, if there's an email found from Fred the Fascist in these compromised accounts, there's likely a copy of it elsewhere.

US Air Force in a seriously stealthless state

Dave Bell

HMS Dreadnought

The point about HMS Dreadnought was that it changed the way naval battled were fought. Even with the same guns on both ships, the Dreadnought "system" had the advantage of a greatly increased effective range. The steam turbines also made the ship faster, which meant it could control the range the battle was fought at,

Only thing is, one ship can't fight a fleet. And other countries had ships being built on the same principles when HMS Dreadnought was launched. So it wouldn't have made much difference if HMS Dreadnought hadn't been built. The rest of the British fleet would have been just as obsolete. And Britain would have to have built new battleships.

Sony distribution centre engulfed by fire

Insurance

There's quite a few things which an insurance company doesn't cover, nuclear bombs for one. It doesn't mean there's no compensation, since the compensation may be paid by the Government.

In the case of Riot, the Insurance company, if they pay out, can claim compensation from the Police. There was talk of replacing the Riot (Damages) Act, a few years ago, but that Act still seems to be in force. And, if you're not insured, you can make a claim yourself.

One obvious example: a lot of vehicles are insured third-party only, and so if they were damaged or destroyed there would be no insurance cover. But the owner could put in a claim to the Police Authority. If they had insurance cover that did apply, they would get a payment from the Insurance Company, who could then claim from the Police Authority.

It surprised me. But all those IRA bombs: the Government paid compensation.

Ofcom report: Mobile operators feel the squeeze

Dave Bell

What data service?

Geography and population concentration means that they have a lot of customers for data services, but they're not where I am. There's voice coverage on the local motorway (I wasn't driving at the time), but data keeps dropping out.

So I really don't have much use for mobile.

Mr Bean prangs £650k McLaren

Dave Bell

Looks pretty bad for the car

The photographs used by The Sun make the car look a write-off. OK, I don't know the economics of this, but no engine or rear wheels visible when the front end is lefted onto the recovery truck: that's a really major job.

As I recall the rules, it's likely to be such a major job that DVLA might not consider it the same vehicle afterwards.

Still, if it came apart on that scale, and the driver was still walking, the engineers did a damn good job.

DIY aerial drone monitors Wi-Fi, GSM networks

Dave Bell

That's the problem

I can't quite make things add up.

It's quoted as being able to fly at 22,000 feet but I'm not sure how long it can stay in the air. That's an electric motor powering the propellor, and that needs a battery. So do the electronics, and there's a lot more there than a control system. Also, you have a fixed-pitch prop, not so good over such a great altitude range.

Anyway, the altitude records I can find for electric model aircraft are well below the claim.

Apple sues NYC mom & pop shops

Dave Bell

I hope they weren't grocers

I have the feeling that British courts are a bit more careful about keeping markets distinct, but it would be a crazy case if these places were not selling computers, even in the USA.

Linus Torvalds dubs GNOME 3 'unholy mess'

Dave Bell
Linux

It's a General Problem

It's not just KDE or GNOME or Unity, I see the same problem in other software.

1: There is a familiar UI.

2: A new major version comes out, with a very different UI.

3: Everyone struggles, and the suspicion grows that the people who designed the new UI have never used the original program.

I'm currently seeing a bunch of programmers getting it right. Not only have they put a lot of effort into making the new UI configurable, they've changed the program name. And some of the changes to the menu structure make sense. Options have been shifted from a semi-hidden "Advanced" menu because people actually use them.

I'm not claiming the results are perfect, but listening to the users does seem to work pretty well.

And Unity? At least we know it's new.

Shetland 'Topiary' suspect extended in custody for 3 days

Access to lawyers

I suppose, with this long trip back to London, a smart defence lawyer could ask some awkward questions about possible asking of questions without a chance of a lawyer being present. And, while it's a UK-wide crime, how does this all interact with Scots law? There's likely nothing new there, but can a London lawyer spot any flaws there might be arising from those legal differences?

Why London and not Edinburgh?

Murdoch muscles BBC out of Formula One driving seat

Dave Bell

The must have given it up!

So we have a contract expected to end in 2013 and it ends early?

Either the BBC was hit by a break clause they couldn't fight (and how could that happen) or they didn't want the rights.

OK, I'm not devoted to F1 but I can see they do a good job. Maybe they have discovered just how big a hassle the Olympics will be, next year. F1 or the Olympics? I'd vote for F1, but that would be so unpopular with the politicians.

News leech loses appeal on High Court copyright case

That sounds bizarre

Just how far along the chain would that end up going. What's next? The customers of the PR companies who are Meltwater's customers having to buy a licence?

Jupiter spacecraft mounted atop bloody big rocket

Dave Bell

Atlas for manned spaceflight?

It's been done.

All the manned orbital flights in Project Mercury used an Atlas rocket.

But about the only thing to have stayed the same is the name.

Russia: 'We'll dump the ISS into the sea after 2020'

Dave Bell

The design is not the object

OK, some of those airliners flying are very old. And they get detailed inspections and thorough maintenance. Soyuz (and its launcher) are built new for each flight.

The ISS is rather more difficult to check and maintain. As it gets older, the crew will be spending more and more time on just keeping it running.

"It's old and can't be fixed" is inevitable, and then you de-orbit the ISS.

Whether it's the politicians refusing the money, or just the pointlessness of flying astronaut-plumbers, the ISS project will end.

UK data watchdog 'looking into' Google+ mission creep

Dave Bell

It is a bit of a stretch...

I'm a little bit surprised by the use of that regulation in this case. Great if it could scare Google back to their senses, but every time the law is stretched to cover a borderline case it can drag in instances we don't expect.

Contracts are sometimes not obvious, and the term is an exchange of value. This could be another one of those dangerous stretches of the law, but I think it's long since being settled. The data that Google is requiring does have a value. Google are creating a mailing list, and they can sell the use of that list.

The problem is that Google don't have to have an RL name to have an identity that can be sold to advertisers.

Dave Bell

That Depends

Private individual: my UK-based registrar doesn't publish my personal data through WHOIS. Name and address is something that pretty obviously comes under the DPA, and the legal advice is that an IP address might do, so it's safer to handle it as if it were.

'Up to' broadband claims out of control, says Ofcom

Dave Bell

An old problem

Which average are they talking about?

I'm not sure than the usual layman's average, the mean, tells us anothing useful.

For one thing, when it's distance from the exchange which affects speed, there's four times as many people at twice the distance,

The median might be different: that's the half-way point, the minimum speed half the customers can get.

I get grumpy sometimes when i see how the available bandwidth to the rest of the internet can plummet in the evenings, Everyone wants to watch streaming video at the same time. The way we use bandwidth has changed a lot since broadband was rolled out, and some of the assumptions made then are badly broken now.

UK Govt refuses to ban shale gas 'fracking'

Dave Bell

Tread carefully?

I don't have a problem with there not being a ban in the UK, but we are talking about processes intended to release vast quantities of flammable gas.

Let's be careful out there.

Mystery data centre snag floors LiveJournal

It is all down?

I was getting some access yesterday. I see good times and bad times, so maybe location, time, and load, all make a difference.

Crypto shocker: 'Perfect cipher' dates back to telegraphs

Dave Bell

What about Western Union?

I have a vague recollection of a description of how Western Union made money transfers by telegraph.

I'm pretty sure that they had some sort of one-time key, but it may have been intended as a signature method.

Ah, here it is. From "The Victorian Internet", p.119: "A running count was kept for each book, and each time a money transfer telegram was sent, the next word in its unique numerical order was sent as one of the words of the message. Another page in the codebook gave code words for different amounts in dollars."

That was devised in 1872, so the one-time element was certainly around. But it's not a full encryption process.

Cellular network hijacking for fun and profit

Dave Bell

One reason why it's so easy

You can't get an engineer to a satellite, so it's handy to be able to use the same tricks as the pirates. You keep the security in a place where you can repair it

TalkTalk drags arse in Ofcom ISP survey

Dave Bell

Same here

That pretty well summarises my experience.

I rather think that the chances of getting good support from any ISP or telephone retailer is getting pretty slim.

Superman beats up cybersquatter

Dave Bell

Reboots are normal

The back-stories for comic-book heroes, such as Superman, have been changed an incredible number of times. This movie instance is a little bit unusual for the time since the last movie, but look at the TV shows which have been around.

Compared to what goes on in that business, Doctor Who has been remarkably subtle. The reboot has become a part of the setting, ever since the Doctor first regenerated.

Ofcom moves: Rural broadband price war on the cards?

Dave Bell
Holmes

Unsurprised by BT

I am currently working on a problem my elderly uncle has.

It very much looks as though the most effective solution is to switch from BT to another retail supplier.

One wonders if BT want to have a retail operation that provides service to ordinary individuals. And, looking at all the ultra-cheap deals on offer, one can see why they wouldn't want to compete.

Asda offloads affordable Archos fondleslabs

Dave Bell

Another word from TV sci-fi?

I think "shiny", in this context, can be traced back to the short-lived TV series Firefly. A piece of invented slang that found a real-world use, a sort of tech-oriented "cool".

Leica X1 APS-C compact camera

Dave Bell

Awkward to sell

I've had experience of Leica cameras for a long time, and they do justify their reputation for quality and durability. Like a Rolls Royce car, there's more to it than the brand.

But Leica don't have such a good record with "compact" cameras. They have been far more about the brand.

OFT probes dodgy sites that charge for free gov services

Dave Bell

Scum rising, as usual

There are a lot of site which swamp the upper reaches of search-engine lists through various sorts of trickery. And government official websites are generally both squeaky clean, and poorly optimised.

What I often see is less a web than a decision tree, which means that the actual pages we want to find, fail to have the features of a well-connected, useful, web page. They're not going to encourage you to click on that Facebook button to signal that you "like" the webpage. They're not going to do anything to get a link from Boing Boing. They are essentially passive.

That can. in some ways, be a good thing. But it does put them at a disadvantage.

Sunday Times accused of blagging Gordon Brown's records

Dave Bell

Something odd here

"I've heard a few journos over the last few days admit that they've had no training on what's legal or ethical in investigations, and their papers don't have rules to consult. So it's all down to gut feeling, what the editor allows afterwards, or you can get away with."

Yet I hear of new journalists being expected to have degrees in Journalism.

Isn't this sort of necessary knowledge part of the degree course? If it isn't, it ought to be.

'Being cyber-stalked is as bad as being raped, or in a war'

Dave Bell

A couple of details...

1: There is, Lewis, a difference between a "trick-cyclist" (or "psychiatrist") and a psychologist.

2: On page 15 of the report, it states that over half the cases in the survey started with an offline contact. That matters rather a lot, if you want to assess how somebody is affected. It's not crazy to worry about the situation bouncing back into the real, physical, world. And, yes, feel free to wonder if that hasn't inflated some of the numbers. Is the "cyber" element just another channel to use?

There's some aspects of the report that seem to come right out of "How to Lie With Statistics", such as the pie charts drawn with perspective.

It's called "Driving Under The Influence", and the only difference between alcohol and everything else is that they have some specific, measurable, limits for alcohol.

Cleaning up the Bitcoin act

Dave Bell

The value of speculation

I do think speculation is far too large a part of modern financial and commodity markets, but there are good reasons for having it. Putting it at the most simple, speculators, buying and selling, mean that when "real" deals are done, there is always somebody willing to buy or sell. And futures trading, both "short" and "long", allows the "real" traders to reduce the risk of shifts in the market.

It was the Baltic Exchange when I was involved in trading some grain futures, as a farmer who was growing the stuff.

A Bitcoin exchange is nothing like that. There's no core reality. And that is a danger. But exchanges need speculation.

News International grabs SunOnSunday.co.uk domain

Dave Bell

Oscar Wilde said it all

If there is one thing worse than being talked about, it is not being talked about.
