OK, team, we've got the big demo tomorrow and we're feeling confident. Let's reboot the servers

Another failed demo

My favourite failed demo was many, many, many years ago when system builds took a long time. Our manager had been given 6 weeks notice of having to give a demo but didn't bother to tell anyone. When he did at 3:00 in the afternoon we were 2 hours into a complete system rebuild to incorporate some core system changes which we expected to break things all over the place.

Crash, bang, wallop: What a power-down. But what hit the kill switch?

SPiT

In case anyone is still reading, the regional control centres that the UK government commissioned for the FireControl project (go look it up) had their equipment room EPO buttons next to the magnetic locked exit door AND they didn't have an exit button for the door so it was the only button present. The situation was in fact even worse than that in that their official process at the time I came across it was to allow third party staff into the room with no means of exit and expect them to phone security to get out, a scheme that didn't even work reliably as during the delivery phase the security office wasn't reliably manned. All in all a rather impressive breach of health and safety and lone working arrangements.

Pirate radio = drug dealing and municipal broadband is anti-competitive censorship

Muncipal ISPs

I'm surprised nobody has pointed out that the american public would have legal redress against a municipal ISP under the first amendment since as part of government they are obliged to respect it whereas the private for profit ISPs aren't obliged to respect it. Seems to me that the threat to the first amendment is the exact opposite of what Mr Oh Really is promoting.

Re: Autonomous weapons

Not only have autonomous weapons been around for decades I would also be much happier to trust an autonomous system properly programmed to decide on an appropriate response rather than some poor grunt who thinks he may die in about 5 seconds if he doesn't press that fire button when it needs pressing. Such humans have something of a reputation for shooting first and reviewing the decision later Unfortunately most arguments against any sort of autonomous weapon are equally applicable to human controlled weapons and whilst I'm sure that most campaigners against autonomous weapons would like to ban human controlled ones as well they aren't so foolish as to imagine they would get wide public support.

Who had ICANN suing a German registrar over GDPR and Whois? Congrats, it's happening

SPiT

Re: "Necessary for performance of a contract"

I would have said that the ICANN argument has got to be along the lines of the fact that the provision of a domain requires registration with world DNS and a condition of this is provision of data to the whois service. This creates an argument that the contract between the site owner and the German registrar allows this because the German registrar isn't allowed to set up the domain without passing the information on. This then leads to a situation where the German registrar is the data controller but ICANN has status as a data processor and needs to comply with GDPR. It does muddy the waters but since the public availability of whois has not practical benefit to the discharging of any contractual obligations and only serves as a convenience I can't see any argument for allowing it other than ICANN claiming that their contract is not subject to GDPR and is covered by US law. That would then mean that no company can legally operate as a registrar in Europe and probably then goes on to the full enforcement of GDPR meaning that no personal data of a European can be passed to/through the USA or be held by a US or US owned company.

I really hope this doesn't turn into the equivalent of a nuclear exchange as it will devastate the world economy but that seems to be the stance ICANN are taking.

Windrush immigration papers scandal: What it didn't teach UK.gov about data compliance

SPiT

Isn't there an obligation for accuracy

See title. By discarding the Windrush data and then maintaining a record of an individual's immigration status which is then, as a consequence of having discarded that data, inaccurate don't we then have a case where the home office holding inaccurate data as a result of their own negligence. Isn't it reasonable to suggest that by discarding the data they have in some way forgone their right to hold other subsequent data on the data subject. I suspect that this question would be extremely unclear in law and would have to depend on action for maladministration rather than just data protection.

For example, this would be similar to me destroying all records of a customer's contract and then when they contacted me for contract fulfilment claiming there was no contract. This would typically end up being treated as fraud with the only defence against criminal liability being a claim of incompetence. The Windrush data was destroyed after the beginnings of a period where the home office had started it's policies that made this data important.

Guess who else Spectre is haunting? Yes, it's AMD. Four class-action CPU flaw lawsuits filed

SPiT

Understanding the real horrible nature of Spectre

For those of you who want to understand the full range of Spectre class faults they come in 2 basic classes.

1) Exploits that use various techniques including speculative execution using branch cache seeding to determine the contents of in process memory which the process is allowed to access. Note that this memory is permitted access according to the processor design model so AMD have a strong defence. The exploit is basically used to break the security model of sandboxes that protect other scripts in the sandbox by preventing the execution of instructions accessing each other's memory. Speculative execution breaks this.

2) Exploits that use various techniques to exploit the basic shared nature of cached information. This applies to the in processor cached stuff (branch predictor, return cache, level 1 cache) and the across chip cached stuff (higher levels of cache). This caches information leaks and this is not preventable without making all cached information private to the process that owns it.

The second class is a serious unfixable problem but it is not obvious how it can be exploited. Just think about it, the only real fix is no shared cache, every cache line is private to the process that fetched it and the fact that it is present is private as well. This basically means a private cache for every core, no dual thread cores unless both threads of execution belong to the same process and a full cache flush on every context switch.

Do you want a Spectre vulnerable CPU or the performance of a machine from 20 years ago.

James Damore's labor complaint went over about as well as his trash diversity manifesto

SPiT

In a slightly different approach, this article contains numerous statements that are manifestly untrue and provable so in court. In particular, they can be proven false to the point that no reasonably diligent reporter could reasonably consider them to be true. In England he would have a pretty open and shut case for libel.

I am seriously disappointed in the Register as they normally take a stance of trying to present the truth. I won't join in with the general mudslinging except to say that I would love to find some anti-Damore article that actually presents actual evidence as after many hours of searching I have been unable to find even a single one. Since his memo is actually available it would be perfectly feasible for someone to point out any of his statements that is, in context, incorrect but nobody has bothered to do so.

All those attacking him are doing a serious disservice to their supposed objective of reducing discrimination as they are insisting that as a society we must ignore the real problems and focus on issues which are either largely resolved or barely ever existed. The current action against Google for discrimination against women is a symptom of this problem. If you ignore the real reasons that men end up getting paid more than women then you end up not doing anything about it.

You can't ignore Spectre. Look, it's pressing its nose against your screen

Can anyone explain why we should consider SPECTRE a hardware fault

I continue to be confused about why everyone keeps talking about SPECTRE as if it is a hardware fault. As far as I can make out the issue is that SPECTRE can be used to read the entire readable address space of your own process. The hardware security promise is that you CAN do this. The problem lies with the whole idea of running a sandboxed program within this environment that cannot see the rest of the address space without having a security rules commitment from the CPU manufacturer. The only sensible way to have safe sandboxing is to have a hardware promise behind it. The obvious solution is for all scripting / sanboxing solutions to use essentially the same solution as for meltdown, make sure that the only mapped memory in the process environment as that which is allowed with the benefit that if you don't have a meltdown problem you can use privilege flagging to protect it.

I appreciate that there are issues around how virtualisation works but the idea that Javascript, for example, wasn't massively exposed to sandbox breaches anyway is madness.

Electric cars to create new peak hour when they all need a charge

SPiT

Total Load

I'm more concerned about the total load in 20 years time when we are all (most) supposed to have switched. If my family switched to all electric vehicles then our annual electricity consumption would roughly double. This is a severe threat to all of the electricity delivery infrastructure and hence needs major national development of the entire network as well as the power stations. If on a national basis we can move to EVs and manage recharging to strictly off-peak to even out demand this could all work quite while but that would be a huge undertaking.

On a more local basis my house has a single 60 amp feed and it would be unreasonable to ever run anything more than a single 7Kw charger off that which would be a major issue for multi-vehicle families who want to charge everything over-night.

We are a long, long way from a viable solution but it is possible to identify all the problems and start considering what should be done. The biggest issue is that this isn't really happening.

Marketing departments really are dumb imbeciles

Marketing departments really are dumb imbeciles. I received several marketing letters addressed to "<father's name> (DECEASED)" after my dad died. The companies involved managed to update their customer databases following a clear cut internal process and yet the marketing team completely ignored this. It is perhaps worth observing that even the GDPR seems to have no real provisions for dealing with this as it is mis-use of the personal information of a dead person. However, if it happened to me now I would be writing back and pointing out that the address was my personal information and that they had no cause to process it the way they had and no registration to use that way and I would be asking for a formal response on what steps they were taking to correct their procedures to make sure illegal processing didn't occur in the future but all that only works because my address as executor differed from his.

UK emergency crews get 4G smartmobes as monkeys attempt to emerge from Reg's butt

Re: Coverage

You might bear in mind, as I've mentioned before against one of these articles, Airwave and EE have completely different definitions of in coverage. For Airwave you a location is in coverage if there is coverage right there where you are standing (outside only), for EE you are in coverage if you can make a call somewhere with 100m of the location. This makes a very big difference as it means a police officer may need to move away from an incident to use their radio. EE effectively has no chance of providing equivalent cover to Airwave which is what the emergency services have been told they will get.

Extradite them

A more interesting aspect of this is to give them access details for a Europe based service. When they use the login details they are then committing an offence as they are not an authorised user (note that typical sites specifically state in their contract that you cannot authorise a third party to access on your behalf). The tit for tat then is to issue a John Doe extradition warrant and ask the US authorities to investigate the IP address being used to commit the offence. It does put USA extradition requests for persons illegally accessing their websites in a new light.

Obviously they will just ignore it but any country that wants to be a pain can have considerable fun with it.

How to nuke websites you don't like: Slam Google with millions of bogus DMCA takedowns

SPiT

Could Google discourage them

This simplest way for Google to discourage this behaviour is to implement (and tell everyone) that it downranks pages for each valid DMCA notice but upranks the page for each false DMCA claim. This of course doesn't work because websites would immediately start "false DMCA" attacks on themselves. But is there some page ranking algorithm, based on information available to Google, that could actually deal with this situation.

For example, Google could advise specific vexatious DMCA sources that they have been classed as vexatious and in future their false DMCA claims may result in page rank upgrades for the targeted site. This would turn into a game of cat and mouse between Google and these people but would give them a serious problem in having to expend a great deal more human effort in managing their DMCA attacks whilst Google's processes could be broadly automated.

Basic income after automation? That’s not how capitalism works

SPiT

Re: AI is a new kind of automation.

This is the key comment in all this discussion. I've just spent 20 minutes finding to prove I don't have to write it from scratch. The key change is that we are facing a future where the combination of AI and robotics could create a situation where some humans are unable to acquire the skills to do a job that returns an economic pay rate. Some people will end up competing with fully automated solutions where the viable pay rate is too low to live on. This has multiple consequences.

As SparkyPatrick pointed out this can lead to an underclass with a ruling human elite. A very popular dystopian future that pervades both literature and visual media. There is however a second issue which is that the true driver of our existing economic system is people buying stuff and when the automated factory turns out many more shoes without any human workers then only the owners are left to buy the shoes and the economy goes into a recessionary spiral. To prevent that enough of the money has to be given to people who will spend it (and spend it fairly promptly). This is the economic argument for the universal guaranteed income and it makes perfect sense. The proviso that changes it from a "that isn't how it works" to "we need that" is the situation where some fraction of the population are no longer redeployed into new roles.

I would suggest that we are seeing the beginnings of this effect with the expansion of minimum pay jobs in the service industry. This is using people to deal with other people because this is were your low paid human currently still wins out. The rise of the automated MacDonalds fast food joint would probably be the point where UGI really needs to be considered.

'Inherent risk' to untried and untested 4G emergency services network – NAO

SPiT

There is also the teeny weeny detail that Airwave coverage is defined as in cover if the radio works everywhere and the mobile networks define in cover as the phone works somewhere within 100m. I have seen a specific example of a Policeman doing his job involving extensive use of his Airwave radio in a location where mobile coverage (as used to call them in the first place) required walking 100m up the hill (and away from the incident). It remains to be seen how that will resolve itself.

Silver Iodide won't work

The basic flaw in this is still using silver iodide. If they really want it to rain they need something that ios known to seed clouds at much higher temperatures which means they should pursuing research on cloud seeding substances rather than delivery arrangements. Unfortunately they probably need to move to biological agents and I can't see them getting that authorised very easily.

FBI says NY judge went too far in ruling the FBI went too far in forcing Apple to unlock iPhone

SPiT

All writs act

The issue in the NY judgement is simply that the FBI have presented an interpretation of the all writs act which permits them to require a third party to do anything that they want as long as the purpose of the action is to aid the FBI in their statutory duty. The magistrate has quite correctly responded by saying that if that is the correct interpretation of the all writs act then the all writs act is unconstitutional and therefore the courts should take a different interpretation or simply refuse on the basis that the all writs act is invalid.

It is that alternative interpretation that is rather difficult. Can you define a general scope definition for permitted writs that includes what the FBI is asking of Apple but excludes outrageous requirements like "Microsoft, we require a complete computer forensics package, please write one for us and hand it over (free of charge)". If the FBI wants to win then they will need to produce a formal justification why the software development work requested is a reasonable request and quite different from my outrageous suggestion above.

The key difference between this and a normal search warrant or subpoena is that it is a request to "do some work" rather than hand over some material evidence.

My favourite sort faux pas

Many, many years ago I had to assist a colleague who had a sort problem. This is in the early days of relational databases on a computer with relatively limited capability. Unfortunately I can't remember all the details (it was about 30 years ago) but he essentially retrieved each record from the database searched for individually to avoid sorting and taking into account the database performance and his program's internal algorithms the execution was order N^4. He requested my assistance because his program worked fine when tested on a 10 record example (although he really should have twigged that taking 2 seconds was rather too long) but when tested on real world data (only 120 records) it just "looped". He did go an fix it when I pointed out that based on his algorithms expected completion time was about 12 hours and it was working just fine. I wish I could remember all the details.

Terror in the Chernobyl dead zone: Life - of a wild kind - burgeons

Chernobyl actual accident profile

Just as a correction to all of you who saw other reactors as being as unsafe as the Chernobyl design and having had similar accidents.

The Chernobyl reactor design has a positive void coefficient. This means that when it loses coolant the nuclear reaction accelerates which is really, really not a good idea. ALL western reactors have a negative void coefficient - if they lose coolant and if you leave it alone it shuts down.

Further, the Chernobyl reactor did not have a melt down, it actually went prompt critical and the explosion in the reactor chamber was a major nuclear release rather than a hydrogen explosion. This was all reported in the atomic energy agency final report but for some reason wasn't considered news and hence did not appear in any of the main stream news media at the time. I suspect that the Internet wouldn't let that happen today.

If anyone is still operating a Chernobyl style reactor they are completely insane and seriously need to stop it right now.

I could make further comment but I really can't be bothered to butt heads with all the ignorant trolls, I'll let the rest of you fight it out as you see fit.

To be fair almost everyone commenting on this thread has a point but throughout the issue down to the idiot minorities. It is virtually impossible to work out which group of road users has the largest idiot minority. My experience of driving outside London is a series of very clear rules to follow

1) On approach to any sort of left hand bend check behind and make sure that you are NEVER overtaken by a caravan on a left hand bend as most caravan drivers seem to imagine the caravan goes no closer to the kerb than their car does.

2) Always look at drivers in side turnings as cyclists are invisible to some people unless you make eye contact.

3) Listen for vehicles approaching from behind and if they accelerate they are probably about to turn left right in front of you

4) Pedestrians are suicidal idiots but they won't kill you

Likely First AIs

It is much more likely that the first AIs won't be embodied systems of any sort - not a specific machine or a robot. Also, the first AIs what be the genuine superhuman AI it will be an "alternatively talented" AI. I would speculate that first AIs and in fact the first problem AIs are going to be created by stock traders in an effort to exploit our financial markets (all of them). There is big money to be made, much more economically than in expensive factory automation, and these will be AIs running on whatever hardware happens to be available. Whoever programs them is going program them to "win" without due regard to any safeguards. They won't be very advanced and hence we are likely to get the problem of badly behaved AIs even before we are willing acknowledge that this is what has been created.

Volvo: Need a new car battery? Replace the doors and roof

SPiT

This idea will seriously upset the local Fire and Rescue Services. They already have a major issue around dangerous components in cars (gas struts, air bags and electrical supplies). The vehicle will need to be designed so that it is very clear to a rescue worker with cutting tools exactly where they can safely "disassemble" the vehicle to release trapped and possibly seriously injured occupants. The emphasis here, is that they have to know what is safe and what isn't. It isn't enough for there to be a safe approach, it has to be guaranteed safe (else their senior management cannot ask them to do it) and it has to be clearly communicated to the rescue workers in a way that guarantees they will be aware.

If you want to store lots of electrical energy (which they do) then this is going to be seriously difficult to make safe.

500 MEELLION PCs still run Windows XP. How did we get here?

SPiT

Re: What about fitness-for-purpose?

Under European legislation you have a fitness of purpose case only against whoever sold you the Windows XP and you'll find that wasn't Microsoft so fitness for purpose doesn't really get you anywhere. And most XP licences will be hardware linked and that kit really is looking a bit old.

The proper legislation is the UK Sale of Goods act which gives a lifetime warranty that the product is fit for purpose and free of manufacturing defects. It doesn't warrant that it is defect free. However, it is a lifetime warranty.

p.s. The Microsoft "we don't warrant that this software is fit for any purpose" doesn't work as a get out.

Google's Wi-Fi sniffing to result in $7 million fine

SPiT

Difficult to make a good case against Google

The real issue is that the only reason that sniffing this traffic might be unlawful is if we are claiming that the users of that Wifi had a reasonable expectation of privacy. In a way its the same issue with StreetView. The complaints about street view photography have been principally around the fact that the raised height of the camera allowed it to see things that people would reasonable expect to not be seen from the street - ie over a 6' fence in a street where no double decker buses go past.

So the real question is do the posters who think there should be a significant fine believe that users of unencrypted Wifi have a reasonable expectation of privacy? Personally I don't know if a court would consider that reasonable or not. I wouldn't expect my encrypted traffic to be private.

And, on another note, cracking the encryption on encrypted traffic would be quite another and clear cut offense in the USA which has a law about "bypassing encryption schemes" and could in all likelihood be treated as a criminal matter where you can't just pay a fine.

Era of the Pharaohs: Climate was hotter than now, without CO2

SPiT

The reality of global warming

The real problem here is that you are all arguing about the details. In a way Lewis Page is perfectly correct to treat the wide range of global warming fanatics with a degree of skepticism. The vast majority of "information" posted by both sides of the debate is at best meaningless crud but more typically distortion based upon prejudice. What currently gets categorized as global warming science is actually the equivalent of weather forecasting but without the short-term feedback for quality control that weather gives you. You find out about 5 day weather forecasting every 5 days. Attempts to forecast climate change details are going to be very difficult and fraught with error.

What this means is that we don't know exactly what will happen or exactly when. This doesn't mean we know it won't happen, which is the typical anti-warming argument. To use an analogy, we are trying to work out whether it is safe to cross the road in thick fog. We can't see through the fog despite the best attempts of current science but we do have a more general theory that is solidly based that says traffic is coming. The warming fanatics are saying we are about to be run over, the anti-warming fanatics are saying that its safe to cross if you can't see anything coming. They are both wrong but I but caution seems more sensible than the gung -ho 'of course its safe' attitude.

The real global warming science is based on sound Geological analysis and a broad confidence that if we keep pumping CO2 into the atmosphere than it will get a lot warmer and sea level will rise and it will make a pretty big impact on human civilisation.

For a good real issue with the predictive science element of the global warming story the best current example is the realisation that the models haven't correctly considered the impact of a reduced equatorial - polar temperature gradient and its impact on the jet stream and the apparent real consequences already seen for weather in the mid-latitudes. This is a perfect illustration of the weaknesses of current modelling and the desperate need to penetrate that fog and find out what is going to happen.

We really don't know how scared we should be. The "it will never happen" brigade should perhaps be compared with the opposite extreme of some of the earlier predictions from James Lovelock of Gaia hypothesis fame (who has since changed his mind). These represent the extreme positions

Adobe demands 7,000 years a day from humankind

SPiT

So what is the contract

The EULA thing is all very interesting because under English law a contract exists if there is an unambigous offer (software made available) and an unambigous acceptance (ticking the box). However, the unambigousness means it must be clear what the parties actively agreed to and this isn't clear on the consumer's side. Also, even when a contract exists the terms are considered to be whatever the two parties reasonably believed them to be. Supplement this with European consumer legislation which basically says the provider has an obligation to make sure the consumer understands what they are agreeing to and you end up with very little.

The bottom line is that where the agreement is with a consumer (non-commercial user) the fact that Adobe (or whoever) can reasonably determine that the EULA isn't being read the contract can be presumed to be whatever the consumer thought it was - ie yippee, free software - full stop, end of agreement.

So as a home user the likes of Adobe don't have a leg to stand on as far as your obligations are concerned. It might give them some slight protection in terms of liability but I suspect that mostly won't work. If you sued Adobe because a flash install wrecked your computer then their defence is going to have to be the common law defence that the consumer had no reasonable cause to expect Adobe to take liability for their use of free software. The EULA simple backs this up as an "if you insist on looking at the paperwork then its on our side" measure.

Is lightspeed really a limit?

SPiT

Not really anything very new

The implications of special relativity are quite simple - lightspeed is a barrier to going faster than light as transition requires infinite energy. On top of that you might also consider that it can be viewed as a theory about simultaneous events and anything going faster than light maps onto a reversed time line. That is, to an observer, anything moving relative to them faster than light will appear to be moving in time. The end result is that transluminal travel creates time travel causality problems.

Bottom line tends to be that there aren't any rules saying you can't travel faster than light, just rules that say you can't get there. The natural 'speculation' is to imagine quantum tunnelling through the light speed barrier but since it is infinitely high this doesn't make sense either. The whole area has been done to death many years ago.

Arctic ice panics sparked by half-baked sat data

SPiT
Boffin

The principal evidence / issue for sea ice loss in the Arctice is not the area of coverage but an apparent substantial reduction in thickness. Unfortunately this appears to be a multi-year side effect from a single really bad year of ice cover leaving it enormously difficult to extrapolate reliably without viewing a lot of data.

However, in terms of public reaction you might like to consider that this years weather is principally ascribed to warming in the Arctic and that therefore this is a very serious issue for the UK.

Warming in the Arctive reduces the gradient of the tropopause between the equator and the pole leading to significant reduction in the energy being pumped into the jet stream. This leaves the jet stream considerably less stable with all the fun events of this year. May be the public are ready to worry about this.

You want the Cloud? You can't have proper copyright, then

SPiT

Have you all missed the point? or have I?

I think the message from this is that something which is accepted as NOT a breach of copyright when carried out with a physical piece of equipment used in the home (recording TV to replay later) is being classed as a breach of copyright when exactly the same activity is carried out via purchasing the service from an online supplier.

To use an analogy, let's speculate that someone has copyright for the recipe for scrammbled eggs and it is generally agreed that you may use it free to cook scrammbled eggs for yourself at home but cafes must pay for the right to do so. Then comes along a service which gives you access to a kitchen on "commercial premise"s to cook your own meals, let's say rented accomodation, and this is then classified as a restaurant rather than an at home activity. Suddenly looks kind of weird doesn't it.

All this seems kind of illegal to me

Under English law the potential employer would have two rather serious issues assuming the Facebook terms and conditions forbid you to share your password and access to the account (I haven't even bothered checking as this is bound to be true)

First

By asking you to hand over your password in breach of your contract with Facebook the interviewing company has broken UK employment law. I'm not sure what the consequences are but you could take them to a tribunal if it is the reason you didn't get the job.

Secondly

Since Facebook have not given you the right to authorise their accessing your account than if they access it (or even just try to access it) they are in breach of the computer misuse act which is a criminal offence. If they ever tried to use information in a legal way that had been acquired by accessing your account it would have to be presented by a witness who explicitly claimed to have commited the offence (not a good move).

Bottom line is Facebook are correct, under English law this actually does amount to hacking.

Antimatter asymmetry: new results bring solution closer

Boffin

Two sided universe doesn't help

Its all very well proposing a two sided universe but it raises the same "who did this happen" question as the matter / anti-matter imbalance and as such doesn't really offer an explanation of anything. It is arguably more reasonable (Occam's razor and all that) to speculate that there is some mechanism that produces an imbalance than to speculate there is some mechanism that will neatly separate matter and anti-matter. You should also bear in mind that anti-matter is routinely created (not just in particle accelerators) and certainly doesn't seem inclined separate itself from matter.

This article really hasn't considered all the implications of E=mc².

The dominant effects will be those representing the largest energy changes in the Kindle and from an electrical point of view this is clearly going to be the issue of battery charge so as you read the Kindle gets lighter.

The next largest effect is likely to be the Kindle cooling off once taken out of your pocket. As it cools it loses energy and hence mass. Mind you this raises the question of what is meant by "heavier" as the reduced bouyancy due to the thermal contraction may actually be more significant. Once you start down the cheesepairing route there are an awful lot of remarkably small numbers to take into account.

There are a lot more things like this that need to be considered before the internal energy state of the flash memory becomes a significant factor.

The myth of Britain's manufacturing decline

SPiT
Boffin

Can't we all be a bit more sensible

The bottom line from the statistics offered is not very exciting really. If everyone referred to the historical economists (who focus entirely on how economies actually behaviour) rather than the economists who constantly look at how to change things the wholse thing becomes rather obvious. The message from the graph is that the UK has had a 1.5% average annual growth rate in manufacturing. For a mature pinacle economy this isn't half bad so no great suprises or concerns there.

The graph was prepared by real statisticians so it doesn't lie about the value of manufacturing in our economy. It is inflation compensated so that increase is a real increase in value. There is one serious statistically issue left open which is whether the graph only includes value add rather than the total exit value of goods. This makes a big difference as our manufacturing is now higher up the foodchain and hence has much more significant material input costs than would apply many years ago when it including everything from the mining / farming of raw materials on upwards. Given the involvement of professional statisticians I would assume that it is value add.

After that all we are left with is that 1.5% per annum tailing of to the present day is a little pitiful against other nations (like China) but it is expected performance. If you are among the richest countries in the world (and we are) then you are automatically at a serious competitive advantage. The main brake on British manufacturing isn't government policy it is the income expectations of the British population* and there is nothing you can do about it..

* Please note British population applies to all those involved in any manufacturing business not just the shop floor workforce. Industry in rising countries tends to have the advantage of consistently reinvesting profits and cheap management as well as cheap shop floor labour.

Air Marshal: RAF may not have to be disbanded

Dodgy RAF

It is worth bearing in mind that the RAF had a good stab at trying to lose WW2 by insisting that independent RAF operations were their appropriate activities. Just consider the following

RAF high command disliked all the spending on fighter command and if left to their own devices would have had a woefully inadequate air defence of the UK in 1940.

Bomber command absorbed a significant fraction of the UK war effort to very little effect. The damage to the German economy was a small fraction of the cost to ours and strictly speaking bomber command lost their air war in spring 1944 only to have it recovered for them by the activities of US daylight bombers (and escorts).

In the 1940-1943 period the RAF had a good stab at losing the battle of the Atlantic. The secret to defeating the u-boats (and it wasn't a secret) was long range air patrols but the RAF felt it was far more important to carry out ineffectual night bombing of Germany than helping the Navy.

The RAF attitude about independent action remains to this day and seriously undermines the effectiveness of the UK armed forces. They are obsessed with their core activity of indepent bombing when the focus should be on supporting the other services in performing proper combined arms activities.

Not as bad as you all make out

The 3dSecure system does have some merit. I have one credit card that is used extensively for online purchasing. If fraud appears on this card then without 3d secure all I have is the claim that one of these web sites has leaked information and it has then be used elsewhere. With 3dsecure I can point out to the credit card company that they have either accepted transactions without a password from someone who knows public information about me or accepted a change of password from someone who knows public information about me. This puts the legal ball solidly in their court instead of the unknown one of many web sites that would otherwise be the only culpable entity.

As far as I am concerned this system worsens the credit card company legal position against the customer as they can no longer offload the issue to a customer versus web vendor dispute claiming they are an innocent intermediary.

Its not the postcodes

that they are objecting to. They are public information but the site is issuing map references for the postcodes. Royal Mail are essentially claiming this map reference data is from their database and therefore is subject to copyright. If the data is derived from their database then the take down is perfectly legitimate.

And all the twaddle about postcodes that everyone is posting is total bollocks

Demise of British tank industry foretold admitted

Tanks for the memory

There seem to be numerous issues to argue with both in the article and the following comments.

Along with so many others I cannot agree that the Sherman was the best tank in British service and cannot believe that nobody has mentioned the Centurion. This was a really high class tank at the time and saw deployment as the war closes. It is probably the best British tank ever but lacks the prominence of other newer tanks or those that saw real WW2 service.

On the other hand all those criticising the Sherman have missed its key primary characteristic - there were lots and lots of them. This and only this is what made it such a good tank.

Moving on, the issue of the obsolescence of the MBT is an interesting subject that could be subject to a much longer article if not a book in itself. The character of armoured warfare has changed a great deal over the last 50 years and whilst the tank killer function of tanks has been largely surperceded the other uses have not. The requirement to drive around the battlefield in a survivable vehicle remains of significance at the tactical level as does the similar (but slightly different) requirement at the operational level.

On reading the whole byelaw item (5) appears to ban the use of mobile phones.

On the other issues of common law, it is technically illegal to stand still in a public place (causing an obstruction) or carry out a conversation involving more than two persons (counts as a public meeting) if you are asked to cease doing so by a officer of the law. The offense in both cases is obstructing an officer in the course of his duties and is an arrestable offense.

Canabis use is a major issue

Strange but it doesn't seem to have been mentioned that canabis use does lead to major problems in our society. These seem to be a result of a wide range of issues all linked to the fact that the product is unregulated and illegal. This is the big issue, bad things happen in our society because of it and no doubt the anti crowd will blame the pot smokers but the pro argument is rather stronger. You could eliminate all the problems by everybody stopping smoking pot OR you can eliminate the problems by making it legal. Both ways wouyld work but I get the feeling that only the second one is practical. Unortunately making it legal is affected by international treaty and so on but the problems are the same world wide. Why can't the human race do something sensible just for once. Are we truly so lacking in common sense.

New Scientist goes innumerate in 'save the planet' special

Both are right and both are wrong

I've read the New Scientist issue and this articles complaint is valid BUT it is also clear that in many areas growth has lead to greater use of resources. This article doesn't actually claim that we aren't over using resources, just that the claim that it is implicit is wrong so strictly speaking the article is right and New Scientist is wrong.

The truth lies somewhere in between, resource depletion is not inherent in growth per se but the real world we clearly are making a good solid effort and ignoring the limited resource issue. One day everyone will wonder why we don't get good sound coverage of this issue somewhere in the middle.

I guess the biggest problem is that the media generally preferes those with definite views rather than those with a good grasp of the problem but no solution. In this case those with definite views tend to be at the extreme end of opinion.

Can't ditch human rights act

The suggestion that the human rights act should be ditched is untterly pointless. The only real effect of this act is to embody the European Treaty on Human Rights into UK law so that it can be applied by a British court rather than the European court. This makes it all a bit less embarassing but doesn't really change applicable law.

As an employer I am conscious that current government advice on what an employer can intercept contradicts the human rights act. This government and its predecessors don't seem to be able work out the balance between human rights and monitoring legislation. They all operate a mish mash of contradictory advice and legislation.
