Artificial Intelligence: You know it isn't real, yeah?

Re: the error is in call it "AI" !!!

"Whatever happened to the term "expert system"?"

From what I remember an expert system made decisions using rules defined by human subject matter experts. Usually those rules were associated with reasons, so an expert system could not only make a decision but also support that with the underlying reasons.

AI/ML (which I know little about) uses statistical analysis to discover correlations. However, most of us will be aware that correlation <> causation. Hence it might be safest to use AI/ML as a tool to discover interesting associations which can then be considered by humans. Furthermore I get the impression that AI/ML cannot give reasons for the decisions it makes/recommends. In my view that makes it unacceptable as a decision-making tool (though it may be a useful decision-support tool).

Re: My money's on Vodafone being the first to start charging

Not necessarily. I've been with Voda NL for ages and, at least for the contract's I've had, I didn't have to pay roaming charges well before the EU ban on them. But your mileage may vary.

(I know it's not cool to defend Voda, but here in NL they provide a perfectly good service at a reasonable price, and local call centres (though I rarely have to contact them).)

Re: Better get Skates on

"voters are questioning the wisdom of letting the EU run everything - the Gillets Jaunes in France are probably the most obvious"

Errmm, as far as I'm aware President Macron was democratically elected, and with a fair margin. However, the Gillets Jaunes are self-appointed activists - i.e. unelected. Furthermore they have been vandalising speed cameras used to enforce road safety legislation put in place through a democratic process. That makes the undemocratic and unaccountable.

Furthermore the EU does not "run everything" and the UK government has form in gold-plating EU legislation.

"the Italians whose DEMOCRATICALLY ELECTED government has been told to toe the line by Brussels"

The democratically determined rules of the EU club include not saddling your electorate (present or future) with excessive debt due to unsustainable spending. (Look what that did to Greece.) If they don't like those rules they can try Italexit, but that also means losing the benefits of being a member of that club.

"threw ourselves on the mercy of the Eurocrats."

Presumably that refers to civil servants - who are rather fewer in number in Brussels than in Whitehall.

Re: Won't someone think of the tomatoes?

"And I guess if we're kicked out of the EU's nuke club, we won't have to buy EDF's stonkingly expensive reactor and could look at alternatives, like Japan or Korean designs instead."

I rather think that construction work at the EDF plant at Hinkley is well underway. Trying to get out of that contract now wouldn't exactly improve the UK's standing as a reliable partner.

Oh, and as far as Japanese alternatives are concerned, take a gander at this:

https://www.constructionnews.co.uk/markets/sectors/infrastructure/energy/wylfa-hitachi-scraps-work-at-nuclear-site/10039046.article?search=https%3a%2f%2fwww.constructionnews.co.uk%2fsearcharticles%3fkeywords%3dnuclear

Basically, Hitachi pulled the plug on this GBP 16 million project because it was way too expensive and the British government didn't want to throw even more cash at it. I rather think nuclear has had its day, is now to expensive and too complicated compared with renewables. And that's even without looking at the costs/problems associated nuclear waste disposal and reactor decommissioning (as it happens I've just finished a little project in that area).

Incidentally, the UK isn't being kicked out of Euroatom, it decided to leave the EU and associated institutions, will of the people, etc.

Re: I hope any fallback systems have been tested for their interconnections ...

"Currently a B2B business doesn't have to charge VAT on intra EU invoices. That will probably change in case of No Deal, I have not found a definitive answer to that yet. Will I need to reopen all contracts to change pricing?"

Just realised VAT is the least of our problems, we're familiar with that and can deal with the changes.

But if you're shipping goods from the UK after a hard Brexit that means importing into the EU and, at best, having to comply with the WTO rules Brexiteers seem so fond of. And figuring out what rules, tariffs and non-tariff measures apply is going to be a bit of a nightmare for a small business not familiar with this stuff:

General info https://www.wto.org/english/tratop_e/tratop_e.htm

Tariffs https://www.wto.org/english/tratop_e/tariffs_e/tariff_data_e.htm

Even just figuring out which Harmonized System code applies to your product is quite a job. It's not just the tariffs as such but also the added hassle.

"Currently a B2B business doesn't have to charge VAT on intra EU invoices. That will probably change in case of No Deal, I have not found a definitive answer to that yet. Will I need to reopen all contracts to change pricing?"

I'm not an expert, but I don't think that's going to lead to any real changes - I think those exports will continue to be outside the scope of the UK VAT system. (You will still have to mention them on your VAT form, but in a different box.) On import the business customer will be charged/charge themselves VAT, and then deduct that as input tax on the next page of their VAT return.

It's more of a problem if you supply goods to consumers in EU countries as they will now have to pay VAT on imports (as they currently do when buying stuff from Canada, China, etc.). So that's going to make you a less attractive supplier to them than one in another EU country. But no doubt this will be easily offset by the increased exports of unicorn jam to keen consumers in Argentina.

However, providers of financial services, such as my professional indemnity insurance, will be totally stuffed. Mine have already informed me they will give me a refund if they can no longer operate under passporting. The one used by some of my colleagues has found a more straightforward solution: they've simply moved these activities from the UK to Germany (so the UK exchequer loses the insurance premium tax + tax levied on the insurance company's profit and their employees' salaries).

Import could be tricky

Hmmm, food and textiles tend to be the most difficult items when negotiating trade treaties - and these items come under both categories. Could take a while to sort out. (And under WTO rules if you let stuff in from one country without tariffs/checks then that has to apply to all stuff from all countries. So no control. Admittedly that's somewhat of a simplification of a v complex issue.)

Re: Most inconsiderate

"Nowadays we've beaten the tobacco smokers, but instead we have those foul wood-burning stoves."

In the late 1970s my gran used to get me copies of Popular Mechanics and Popular Science, the American magazines. I'm pretty sure they used to include articles and ads featuring wood-burning stoves with catalytic converters. A quick web search suggests those are still available, perhaps someone ought to tell Michael Gove. (Incidentally, those magazines also ran interesting articles about solar energy and energy-efficient houses (often earth-sheltered).)

Same here in NL (though I haven't come across that much porn in the newsagents here). Teenage pregnancies lowest in the EU, 3.2 per thousand (UK: 14.4).

Re: Why Dublin?

"But only the UK selected it as its official language."

I actually went to a talk about language and the EU a while ago. A retired EU translator explained that the status of English as an official EU language is actually established by one or two treaties, so not dependent on the UK being a member state. Hence English can continue as the lingua franca of the EU, having replaced French in that role some time ago.

"Just, with UK exiting EU, why UK telcos are submitting the issue to EU??"

Because the UK is still in the EU :)

And rather a lot of industry bodies want to stay involved to avoid the need for new British regs and duplication of work. BSI for example:

Interesting quote from the Construction Manager article:

How they do it in NL

"This will mean – among other things – companies will have to update or buy in new, compatible software."

VAT returns have been digital for yonks here in the Netherlands. If you use an accounting package you can use that. If not, or if you use a homebrewed system you just go to a web form and enter the numbers in a few boxes. Takes about 5 mins (if you're a slow typist) every quarter. Can't fathom why HMRC can't copy that approach. But UK bureaucrats always seem to find ways to make life unneccessarily complicated. (Don't get me started on jobsworth-pseudo-health & safety stuff (in contrast with real health & safety stuff which I'm all in favour of).) Time for a beer to soothy my nerves!

Great idea. I always fancied the having the control panel of an IBM System 360 (about the same vintage as me) as a wall decoration, but haven't found one so far. However, I have inherited some of my late father in law's vintage electronic components which are much more photogenic (above-mentioned pretty colours, etc.) than modern ones. Might get the macro lens out one of these days and photograph them.

Possessed CD player

Didn't happen to me, read about this on a theatre sound mailing list:

When the sound operator sat at the sound desk, the CD drawer of the CD player on the other side of the booth would open randomly. If the operator walked to the unit and pressed Close the drawer would stay closed while the operator was by the CD player, but would open again when they walked away from it.

They eventually discovered that on the shelves on the opposite wall a heavy book had fallen on the CD player remote control, pressing the Open button if there was any vibration. However, when the operator was standing in front of the CD player they would interrupt the IR beam, hence the drawer would not open at that time.

Re: Think of it this way

"While DJI do make consumer drones, they're hardly toys anymore, they've made a huge dent in professional markets."

Yup. Currently working with a drone company and learning a lot about this kit. Just over a grand will get you a DJI drone with a pretty good camera. Perfectly good for many photography and video applications, and some surveying jobs.

Also gets you DJI geofencing. Stops you from accidentally flying your done into restricted airspace (potentially saving you thousands in fines, and zillions in damages if you shut down a major airport with a drone incursion). But the geofencing is not perfect. One operator I know is based at a _former_ military aerodrome and for ages the geofencing map wasn't updated and stopped them flying a DJI drone at their home base. Also means that DJI can potentially map your whole country as restricted airspace and shut down your drone operations completely. So perhaps not the best brand to choose for public services applications (go on, call me a cynic).

Here's to a good weekend - may your pints and drones have a safe flight.

Although at first the large number of parties in NL and the fact that you always need a coalition might seem a recipe for chaos, it does seem to work quite well. One of the advantages is that there is more consensus within each party, fringe elements can move to another party.

A few weeks ago Mrs H (recently arrived in NL) and I watched the presentation of the budget. What stuck us is the modesty of the politicians, a welcome absence of selfaggrandisement. Specifically the Minister of Finance started his speech by praising prudence, he then mentioned that the economy is doing well but that this wasn't just due to their hard work but also that of previous governments and the world economy doing better. And it seems that NL is one of the few countries to run a budget surplus and paying off the national debt. Guess Mrs H and I will be staying here for a bit longer.

Are you sure about that?

"Ok, now explain why a surveyor working in the middle of a field has to wear a hard hat, hi-vis vest and steel toe boots. "

They don't. But to avoid arguing it's easier to get people to wear them all the time. And many folk think they know health and safety law but actually only know fragments of it, and many myths - resulting in them focussing on talismanic, visible stuff like hi-vis, but igonoring real safety.

My personal bugbear is pointlessly wearing hi-vis vests when working inside buildings on a site where there are no vehicles operating (inside or outside). But that's mostly a UK thing :) (In NL they wear hi-vis too rarely, which also annoys me - guess I'm easily annoyed.)

US government use of AI is shoddy and failing citizens – because no one knows how it works

H in The Hague Silver badge

Re: re. no one knows how it works

"well, I suppose AI does know how it works!"

I don't think it does - that's the crux, it can't explain the reasoning behind decisions. And I get the impression that often there's no reasoning/intelligence, just statistical analysis. That can be a useful tool to make statements about a population, but not for making statements about individuals. Furthermore, using inappropriate training data is a clear example of Garbage in - Garbage out. I thought that most of us would have learned enough at secondary school to appreciate both the statistical and IT flaws but I'm probably naive.

Incidentally, today's populists seem to complain a lot about "unaccountable bureaucrats" (who actually implement rules set by the legislature) but not about "unaccountable AI" (which implements opaque rules, if any). Why?

Figured I could just go into the corridor, pop up a few ceiling tiles, stick my head up the void/plenum and adjust the damper in the ventilation duct.
