"A set cannot be a member of itself" -- DavCrav

(Apologies to Bertrand Russell and the very large set [or class] of people whose maths is better than mine if I've got this wrong but I think that ...)

... this is equivalent to saying that "the set of all sets that don't contain themselves" is the same as "the set of all sets" But clearly, because the set of all sets does contain itself, your statement is self contradictory.

In practice I seem to recall it is undecidable - you either say you are working within a system where sets can contain themselves (ZFC) where the ZF refers to Zermelo and Fraenkel and the C stands for 'Choice' (as in the Axiom of), or you say that you aren't.

Bonus AofC joke:

Q) What's yellow and equivalent to the Axiom of Choice?

A) Zorn's lemon.

"unusable to people who are red-green colorblind" -- Michael Wojcik

Did you mean red/yellow/blue button? That's hardly unusable to the colourblind once you know which button is which finger. Unlike the (still) unusable pastel shades that are the defaults for much of Excel graphs and Powerpoint templates.

A Smalltalker who cannot easily write in any other OO language (OK, they might tut and sigh a bit) doesn't really know Smalltalk. There's almost no language in Smalltalk (three reserved words) and almost no syntax --- it's virtually all paradigm.

"It does seem somewhat ridiculous to have one's feet fixed to the pedals...if riding in city traffic." -- Fraggle850

... Or, indeed, in the country. Slowing for dog on a transverse vector, I wobbled into an electric fence and lay there with my feet fixed to the peddles getting a blast of twitching every two seconds as the fence continued to operate normally.

"while women are programmed to choose a dependable partner who sticks around." -- Archivist

Speaking as an erstwhile geneticist, that's not strictly true. There's a considerable advantage to women to play it both ways, and significant evidence that they do. The optimum mating strategy for a women is to become impregnated by an extremely attractive (and likely promiscuous) male and then have her family provided for by some dependable saddo with material resources who is unlikely to cheat.

Re: Sexist, but joking = Sacked

I didn't support him being "sacked" because it's not how academia should work: the #distractinglysexy response from female scientists was much better.

Nevertheless: there's a bit of a difference between being apparently serious and being obviously ironic; there's a bit of a difference between being a satirical news source and being a brand ambassador for an institution; and there's a bit of a difference between being fired from a job with teaching time, lab-time and a salary and being asked to resign such a non-salaried brand-ambassador role when you've put your foot in it big-time and embarrassed your brand.

Virtual machines?

I'm not expert enough to make much sense of my search results, but I was under the impression that ORACLE support had a few limitations when running on VMs -- specifically that they will not provide support for any issue that is not known to happen on native O/S unless the user can demonstrate that the issue is not related to the use of, for instance, VMware.

It's not quite 'insisting on physical machines' but it does seem to me (again, not an expert) that this may be a bit of an out-dated attitude. Would much appreciate comments from the knowledgeable...

Re: FFS

"You missed this?: "Each device scored one of the three pockets in the back of my club jersey. I couldn't turn them on and off simultaneously, but started and stopped each within seconds of the others." --- JeffyPoooh

You're right, I did miss that. But it's still only one run per device, so whilst my off-the-top-of-my-head suggestions for variance were wrong, I think my complaint about the test method still stands. Several runs with the same three devices are needed to determine what the intrinsic variability of each device is before meaningful comparisons can be made between them. Otherwise you end up with the "Which? effect" where, because one particular washing machine, vacuum cleaner etc. outlasted another, they mistakenly think they can form judgements about longevity of each model.

FFS

All journalists should go to science, or at least stats, school. Not only are the discrepancies here effectively negligible (you really didn't think GPS was millimetre perfect, did you? I was actually amazed about how close they were!) but as you've only done each run once you have no idea at this stage whether the variability you are observing is due to the runs being different (different times of day, different 'wiggle' from the precise route, or even just random error) or whether it is significantly different between the devices.

"What's the point of responses that go 'this sounds like a bad idea because <insert completely unrelated use case for another much more data-intensive country>'" -- Raj

Sorry, Raj -- I think many UK readers will find the idea of the government making a quick fix response to protect consumers from telcos such an alien concept that it will make their heads spin. As it was a quick fix, I don't suppose there's much to stop them refining the rules quickly in future as circumstances change. But from the point of view of someone who lives in a country where the 650 idiots in the building with the clock couldn't come up with a useful, even if somewhat flawed, regulation within the lifetime of one parliament, it's very confusing!

Re: The only way to not be ridiculed...

Reminds me of the old joke about when the French Resistance didn't have enough guns and new recruits were given broomhandles for training. But one day the Germans surprise them and the poor old noob has to defend the secret bunker with nothing but a broom handle. Bizarrely, he finds that taking careful aim and shouting "bangety bang!" is actually *working* and the oncoming hordes are dropping like flies. However, there's too many of them and they are nearly upon him. That's where the bayonet training kicks in and, amazingly, poking the chaps in the ribs and shouting "stabety stab" seems to be doing the trick. On all except one attacker; he just keeps rolling on towards our plucky hero. Just as the latter is about to be literally trampled by one remaining slow moving assailant trundling impassively towards him he shouts "Hold on, why aren't you dead?" The German replies: "Clankety clank, I'm a tank"

front projection

Agreed --- Most 'home cinema' is just 'big telly' - but with a small amount of effort you can get a projector to give a truly gorgeous image of any size you like. You don't even need to have a home cinema room. When our projector is off, it just looks like we have a modest 23" IPS monitor to display one of the inputs (SKY / Pi / PS3 / Wii). The projector only dominates the room when it is on - which is when you want it to.

You don't even need an expensive projector - I got this 720p SONY 3LCD one off ebay for a hundred quid. OK it's not as good as my sons' Full HD / 3D Optoma, but it produces a great picture (and warms the room in winter)

What? Which members of this brigade let their children out after midnight? Here in rural Warks, our lights go off at 00:00 (01:00 on Sat and Sun) and it's marvellous.

"Sorry, but when you have people blowing themselves up and killing people... I'll accept limited snooping if it means I can sleep safe and bomb free." -- Ian Michael Gumby

We have pretty much established that limited snooping does not mean you can sleep safe and bomb free, so your statement isn't really very useful. Do you mean you would accept vastly more snooping, i.e., the amount that would allow you to sleep safe and bomb free? I think the amount of snooping required to achieve that is effectively unlimited. Or do you mean that you won't accept any snooping at all if it doesn't allow you to sleep safe and bomb free? Both positions seem ridiculous, but if you don't hold either of them your conditional statement is effectively content free.

"... but I'm pretty sure that the technology is still being developed ..." -- moeity

Trouble is ... the maths is already developed, so it really doesn't matter what you do with the technology. There are too many people and too few terrorists, so if your false positive rate is anywhere near the realm of the possible you will have far too many leads to follow (a "99.99% accurate" test would give you 3,000 leads in the UK alone - it would take something like 30,000 field operatives --- and probably another 10,000 support staff --- to keep an eye on them 24x7).

Re: Again?

Principally as a result of Tim Worstall's articles, I have actually found myself reading Adam Smith's "The Wealth of Nations" It's hard to recommend this too highly -- it's a very rewarding, if not entirely straightforward read. It is especially interesting how he railed against allowing special interests too much control, or even just influence, over governments. In particular, he talks of "corporations" which, as I understand it, then referred to businesses who use government law to restrict competition in order to gain financial advantage --- that would seem to describe the medallion issue in the article perfectly.

"The quoted definition is a horribly poor one anyway" -- DropBear

Yeah, it's a particular bugbear of mine. At least it wasn't mis-attributed to Einstein, which is the usual state of affairs with this (mis)quotation. It actually seems to have come from an Narcotics Anonymous pamphlet (page 11 [25 of 68] of this pdf) which contains the more sensible "repeating the same mistakes ..."

Anyway, every time I see it, I have to complain: it's right up there with "everything happens for a reason" and "everyone's entitled to their opinion." I keep thinking there should be a pithy retort along the lines of "you clearly can't tell your perseverance from your perseveration" but I'm still looking for something effective.
