Re: and talking about cars...

But cars nowadays don't quote horsepower, they quote that crucially important figure of PS ('Pferd Stark').

Oh, hang on, when I translate that from German it comes out as Horse Power. Damn!

Re: Imperial to Metric and back again

Boats and planes generally don't use miles for navigation. They use Nautical Miles (approx 1.1 statute miles) for a good reason.

Nautical miles are based on the size of the earth and the not-unreasonable approximation that the earth is a sphere. If you accept the idea of 360 degrees in a circle and 60 minutes in a degree, you discover that minute of latitude corresponds to one nautical mile. This is not an accident.

It's entirely reasonable to argue that the nautical mile is a much more 'natural' measure than any invented measurement such as the imperial mile or the metre (which was itself originally (allegedly) some arbitrary division of the distance between Paris and the equator, or similar nonsense).

If only we had been born with 12 fingers, we'd be spared the decimal fascists who can't comprehend that there are, actually, better number bases to work from. Now, how many pennies would that actually give to the shilling? Oh yes, I remember ...

Re: Napoleon and his metric system conquered Europe,

I'd also point out (no doubt to be corrected) that bicycle tyres the last time I was in Germany were measured as things like 21 Zoll. To the best of my knowledge 1 Zoll is equal to 2.54cm which is pretty close to an inch.

Algernon

@Graham Marsden - thank you for reminding me of one of the most moving short stories I've ever read.

For those to whom the reference is a bit obscure, look up the Hugo Award winning short story 'Flowers for Algernon', or at least read the Wikipedia entry if you are too lazy to read the story.

There's even an eery resonance with the subject of The Register's item.

Re: Re: Re: And a more mundane consequence of non-jamming

Using a sextant isn't going to be easy to navigate an ambulance. It might get you close enough to ask a local for directions - in anything other than ideal conditions and your watch being spot-on, you do well to get a fix to about 3-4 nautical miles and based on my own experience, even that's a fairly ambitious ask. Without a natural horizon you need to use an artificial one (a bed of mercury or a bubble spirit level seems popular) and that doesn't help the accuracy either.

A true but sad story

I started teaching programming language courses in 1977 in a British University, initially FORTRAN and BASIC (ugh).

I then moved to commercially teaching C, then C++ then PHP programming as fashions changed. The age of students coming on commercial programming courses varies, but didn't change substantially and would typically be mostly in their twenties to thirties.

I stopped when an old stalwart exercise became unteachable: having shown students variables, loops and output statements, they were given the simple formula and then asked to write a program which counted 0-100 and printed that value, plus its equivalent in Fahrenheit if it were a Celsius temperature.

For years that was one of the ease-you-in starter exercises, total time expected about 5 mins including getting a biscuit to eat while you did it.

My disillusionment came when increasing numbers of students would look upon this exercise with blank faces. I well remember the first time I said:

"Ok, I've shown you variables, statements and loops, how do you plan to do this exercise?"

Answer: "You haven't show us how to do it"

Me: "I've shown you the tools you need and the formula, how do you think you might start?"

Them (baffled): "But you haven't shown us how to do it"

And that was when I realised what British schools were now turning out. The difference in attitude and approach was truly striking.

I stopped teaching programming courses not long after.

Would love a standard for speed limit data

Whilst doing this I wish the wonks would come up with a standard for defining road speed limits and the areas they apply to.

The gentle 'bong' sound from my TomTom is a VERY useful adjunct to eyballing speed restriction signs.

A UK (or EU) standard for publishing that data with a statutory requirement to publish it (and a get-out for an offending driver if its not up to date or is incorrect) would be a much greater contribution to observing speed limits than any number of speed cameras.

I think I'd work hard to keep that information up to date.

Emacs

There was time, long long ago, when the joke acronym for EMACS - Eight Megabytes and Constantly Swapping was very funny, because 8 megabytes was incomprehensibly huge.

How times have changed.

A nice bloke too

I was fortunate enough to have visited Bell Labs and met Dennis Ritchie (along with Ken Thompson, Brian Kernighan and Bjarne Stroustrup) in the mid eighties. What struck me, apart from the sheer intellectual horsepower he had, was what a nice bloke he was too.

Having had the opportunity to share a beer and a pizza with him remains one of the more memorable moments of my professional life 25 years or so on.

The work done by the Unix team (and he'd be the first to acknowledge the huge input of less well-celebrated people like Joe Ossana, Bill Plauger and many others) did change the world I knew, and in most respects for the better.

Mike Banahan

Sextants etc.

I think you might find something along those lines - using a digital camera as an emergency sextant - in The Lo Tech Navigator by Crowley combined with the excellent Emergency Navigation by Burch.

Problem is, a single sextant reading can only give you a line of position (long line drawn across your chart) and not a fix where two lines cross. Admittedly, if you can do that then it helps anyone searching you a lot as they only have to look up and down a line instead of hundreds of square miles of sea.

I was thinking of doing an solar navigation app for my Android, but hadn't thought of trying to combine it with the camera ...

@CaptainHook

Be careful about believing everything they tell you on the course.

Get a hive full of Fen Bastards (the affectionate name for the local wild black beasts we have out in six-toe territory) and they'll fly at ridiculously low temperatures. A bright frosty day has mine out and not just for a poo, they came back with snowdrop pollen on their legs whilst the snow isn't even melting on the ground.

Admittedly, I've never seen them trying it in fog. Maybe it's time for a pissing contest "My bees will fly at lower temperatures than yours" etc. :)

DIY vs call a plumber

Declaring an interest in this, since it's what my company does for a living, I'd say you need to be near-crackers to do this yourself.

It's not just about virtualising stuff, it's about knowing in advance what works and what shouldn't be virtualised. There are some applications that cry out for their very own fat client PC (badly behaved memory and cpu hogs) which, if they are mission-critical for the user, are going to be very bad news.

Also, a good design would split off the users who need full virtualisation from the (probable) majority who will be entirely happy with something like Terminal Services, a very much lower cost option.

I'm highly sceptical of involving just 'consultants' who don't know what they are talking about, but when you can find real subject expertise out there, it's foolish not to draw on it.

And there are plenty of solutions which don't involve replacing all the desktop real estate at once. Consider gutting your existing desktops and turning them into thin clients if the exorbitant price of bespoke thin client devices looks too high. You get the management cost benefits if not quite the power saving.

This isn't rocket science - but it's a specialist area and what's the point of discovering all the 'well known' problems for yourself?

Mike Banahan

Anybody got a sextant?

And (for ships at least) an accurate watch, a sextant and knowledge of how to use it will get your position to within about a mile. Unless it's cloudy, oops.

I doubt if any aircraft still carry them or have anyone who knows how to use them.

Ebay usually carries a few - I've tried a plastic Ebbco for £20 which isn't much less accurate than a Freiberger I picked up for about £350. The latter is a fabulous piece of optics and engineering but overkill for a casual sailor.

Shome mishtake shurely?

According to my reference books here, tomatoes are predominantly self-pollinated and don't rely on any form of bee, honey, bumble or otherwise.

For futher reference: http://gardening.wsu.edu/library/vege016/vege016.htm

Not saying the article is necessarily wrong but when one spots an obvious and easily avoided mistake, that doesn't exactly increase confidence in the rest of the article

Prosecution is also a form of punishment

I'd like to see something about the disproportionate disruption to peoples' lives be taken into account on this as well.

Let's say that McKinnon's situation has been reasonably fairly represented as minor and probably in the uk for a first offence liable to lead to, say, a fine of around a thousand and couple of hundred hours of community service. I'm not saying that this is necessarily appropriate in this particular case, it's a for-instance argument. That's a substantial punishment for many people.

But as a punishment it's nothing compared to the harm and stress that would be caused to all but the most extraordinarily resilient person by their forcible extradition and then prosecution in a foreight court along with the total disruption of their life, employment, family and all the rest. For the ordinary person you are going to lose your job - certain. You have a house and mortgage? Oh, bad luck on that one, but hey, if you get off you'll be back in two years, no harm done, you will be able to pick your life up again. Your wife left you while you were on remand in the US and has taken the kids? Bummer, but it's easy to produce kids, just get another woman you love.

Now I know that that's not appropriate in this particular case but surely only the most absolutely heinous kind of crime should even be considered suitable for extradition? The process itself is a ghastly form of punishment that you receive whether guilty or innocent.

Black Helicopters

Of course we believe them

Let's say the Feds did manage to crack the data. Would they want to tell everyone that they did or would it be more in their interest to slide out a deceptive story saying 'Oh no, we can't crack Truecrypt' to discourage others from using something stronger?

Maybe they now have a lot of information that they can use to uncover other evidence which mysteriously seems to have come to light anyhow, nothing to do with that encrypted data, honest.

There's lager then there's the piss they sell in England

After living for a year in Munich and spending most of it in beergardens and similar establishments I find a bit of contrition is necessary. A firm believer in 'the British make the best beer in the world' (actually they do, Taylor's Landlord) I learned that whilst maybe the pinnacle belongs to Blighty, the quality is found in Bavaria - I can't speak for the rest of Germany as I didn't explore further.

It's remarkably hard to find a bad beer there and the consistency and quality, not to mention the welcome, is excellent.

And anywhere else when they sensed a bunch of beer-swilling chavs descending from all parts of the world they would rub their hands, see the till signs go up, and serve the worst they had to the undiscerning louts of the globe. Not at the Oktoberfest though - instead of selling the weakest piss available, the Oktoberfest special beers are not only excellent, they are extra strong at typically 6%.

A well-made litre of Helles (lager) is so far from what you can get in the majority of pubs in the UK there's not much comparison. Though I still prefer dark beers, even I, with my chauvinist hat on, have to concede that it's a beer-drinker's paradise over there.

Sorry and all that but sometimes a bit of reality is called for.

I went back a week ago to check. Nothing has changed. Top food too.

Only speeders should worry

I used to feel that way about speed cameras (only those who speed complain) till I had to drive on a wet and windy night from Leeds to Shipley.

You have to try that road. The limits vary from 30, 40, 60 almost randomly. There are some substantial clear stretches where any prudent driver is going to assume that the limit is 40 and when you are straining your eyes to drive safely it really is the last thing you want to do to have you attention focused on the apparently arbitrarily placed limit signs - as any fule no it's not exactly going to improve you attention to other vehicles, pedestrians, cycles etc.

So you are, you think, by any measure driving safely. Then poof! A bright flash in your eyes because you thought you were absolutely obviously on a 40 mph stretch but no, points on your licence and a fine.

What seems so unfair is that you will observe some lunatic dangerous driving of other kinds that isn't caught by the cameras whilst your sensible approach to managing your vehicle and speed is punished.

Now I have to say that in fact I didn't manage to trigger a camera when I did that drive, but I felt that it was actually more dangerous to focus on the speed limit signs than to judge a prudent and safe speed based on some 30 years of driving experience.

And that is what changed my mind about the 'only speeders need worry' response.

As it happens - cross fingers - I've never had a speeding ticket but that stretch made me hate the cameras because I felt they made the driving more dangerous, not less.

Anecdotal stuff

I lost one of three but it was weak before the winter started and despite feeding it gave up in January.

I can vouch for the high swarm level this year - had one very strong colony and one marginal in February, by April the strong one had to be split which should have prevented swarming but the queenless side of the split has thrown four swarms in the last week, getting on for a record even for our local famously productive black bees (colloquially known as fen bastards as a nod towards their ill-temper). Looks as if they had made up their mind before the split ... luckily I was around to capture two of the four and hive them. Given the fab weather the virgin queens will presumably have little problems mating either.

Here's to a LOT of mead in the autumn - hence the glass!

@john murgatroyd

I'm told that the scratters from our local estates sometimes gather cigarette ends from outside local pubs, where the now-banned smokers stand, and drop them at burglary sites to pollute the DNA evidence. The funny bit is that most of the local pubs where they collect those from are pretty exclusively patronised by crooks and drug -dealers anyhow.

@Red Bren

I second the call for a brown (funny name that) paper envelope icon. There's way too much casual corruption in our system these days. I don't think there is a lot of overt corruption, but the 'we have always done it this way' gradual creep of institutionalized corruption.

Like MP's expenses as a classic example.

The Payroll Vote (look it up).

Our political system is corrupt top to bottom but it just doesn't realise it. Intellectually and morally corrupt, not so much direct bribery.

Why keep the DNA?

What's wrong with collecting and filing the DNA profiles on all unsolved crimes, then when poor Joe Public is arrested and swabbed

- check to see if he's one of the wanted ones

- if not, delete the sample

Since by all accounts the great majority of crimes are committed by a small number of diehards this would quickly sieve most of them out AND act as a big deterrent to someone guilty but as-yet -unpunished to not do anything that might lead to arrest

Since I care, frankly, much more about preventing future crimes than those already commited (you can't uncommit them and punishing people seems an expensive waste of time) doesn't this actually achieve what we want?

Maybe I've missed something ... sure someone will enlighten me

Traditional hackers' diet

I've long supported the tradition of beer and curry myself, with devices named tiger, landlord, cobra, balti, korma, roti ... it's enough for a modest network as long as you don't fall into the trap of naming the currently-hottest one vindaloo or phal only to be embarrassed a few years later when you realise it's now as comparatively spicy as a raita.

Mike Banahan

Responsibility of politicians

Here if ever the case was the need for legislation (and an outside body controlling it) which places a duty on ministers not to indulge in contracts which, in the view of the courts, contains clauses tantamount to poison pills. If a minister willingly signs a contract which unreasonably constrains a later change of government, they should be legally responsible for that with severe criminal penalties.

Job done.

MPs in the dark ages

I don't believe all this cock about having to be in Westminster. Yes, in the 18th century there was little choice - but there is increasingly little need for a physical presence in a place like the houses of parliament nowadays.

One of the businesses I'm involved in no longer has any office at all - all staff work from home and with a mixture of VoIP, Skype, instant messenger, email, phone and shared online documents we communicate much more effectively than some companies where everyone commutes into central offices. A member of staff moved to Dubai and the only difference was that he got his salary tax free rather than taxed and the company stopped having to pay National Insurance for him. Apart from that there was zero noticeable change on the work he did or the way he worked.

If the MPs got their act together a similar thing could replace a large amount of the 'we have to be there' cobblers they seem to believe. It's time for them to change working practices rather than sticking to their outmoded antiquated working methods.

Mike Banahan

@Jolyon Ralph

That'll be a swarm - how bees reproduce. The colony grows in spring, produces a new queen or three and a goodly chunk of the existing bees plus a queen go and look for a new place to colonise while those that remain in the original hive reproduce like fury to make up the numbers again.

It's a strange time of year. I lifted the lids on my hives yesterday and instead of the early-season numbers I expected they were bursting at the seams replete with swathes of honey. Mind you, the rape is already in full blossom locally so it's probably all rape honey that will set solid now the weather has turned cold. Time to split them and double the numbers before the beggars swarm.

Mike Banahan

What would really help ...

.. would be some proper scientific action.

The amount spent on the National Bee Unit can't be judged in context unless we actually know what happens if we lose the bee population. Ok, I'll be sad if my colonies die but it's not the end of the world for me. However, if that badly affects the overall food chain that is REALLY SERIOUS. And all I have ever seen is speculation as to what it would mean in practice. How much of our food is critically dependent on bee pollination and would anything else fill the gap?

Alongside that it would seem a useful precaution to siphon off a gnat's cock width of the ridiculous billions being pissed away on ID cards and Connecting for Health and invest in some serious work to try to breed Varroa-resistant strains (ideally) or failing that, a miticide that actually works. And whilst on the case for that, try to find out whether we really do have other problems affecting the bee population since as far as I can tell all we really have is a lot of anecdote and confusion at present.

There's a limit to what amateur bee keepers can do no matter how motivated they are. Protecting the security of the food chain however - now it seems to me that's one of the reasons you might want a government.

Feed of Diana's death

Shock, horror - OMG - an unencrypted feed! Who would have thought that they would ever exist?

Apart from EVERY F*CKER who had a steerable dish in the nineties. There were hundreds of clear feeds used for TV news gathering, even whole columns dedicated to spotting them in the satellite magazines of the day. On a poor day for official programmes, it was often more fun to point the dish at, say 1 degree west, and watch the UK-US news feeds then see them pop up edited on the news later.

Now things have gone digital they are more likely to be encrypted but when Diana went titsup that was probably the exception rather than the norm.

Give us a break.

Us power

I thought the US power supply was typically two-phase 110volt. Low power circuits run on 110 volts off one phase, high-powered heating and cooking equipment uses both phases for 220v.

In that case, no transformer is needed, though a 220v spur would be needed off the distribution board into the garage or wherever.

@chrisc

If the rogue 'secure' site serves up a certificate for www.bankofamerica.com that certificate still isn't going to be signed by a trusted Certificate Authority so the punter will get a warning pop-up. Some will probably click through so the goal will have been partially achieved.

To overcome savvy users you would need to get a rogue certificate signed by the CA. That's not going to be easy for an obvious name like bankofamerica.

However, given that you can get a server certificate for peanuts nowadays just by waving a credit card and if you go for a domain name like bnakofamerica.com (i.e. a typo) or, as Alliance and Leicester seem to do, direct to an unrelated domain name (mybusinessbank.co.uk) then it will be a lot easier to have a domain with matching and signed certificate. It takes an alert user to spot that one.

Lots of scope for tricking the punter here! This looks like a pretty nasty vulnerability.

"Given the use of anti terror law to freeze Icelandic bank assets there is no doubt that this mega database will eventually be put to use against benefit fraud and parking fines"

Charlie mate - that's why they are doing it in the first place. It's nothing to do with terrorism it's to do with tax collection, benefit fraud, money laundering (in distant 3rd place) and then anything else they can do to stop us doing what they don't like.

@SkySkoll

PAN PAN is the approved way of writing the Urgency call. If you take a look at the Civil Aviation Authority (that's the UK one) document CAP 413, "Radiotelephony Manual" chapter 8 states:

1.2.2 The pilot should make the appropriate emergency call as follows:

a) Distress 'MAYDAY, MAYDAY, MAYDAY'

b) Urgency 'PAN PAN , PAN PAN, PAN PAN'

Yes, it's based on the French (apparently) but not spelled that way in the official blurb.

Techno gibberish

Out of interest - in what way is email connected to running websites? Mail servers are typically in no way related to web serving and are usually in entirely different locations on completely different networks.

This sounds (on the face of it) like complete and utter bollocks being spouted by a clueless numpty.

Mike Banahan

@AC - Why?

People should ask for the circuit diagrams too. It's not good enough to calibrate these things on standardised samples and then argue that that 'proves' they are accurate. For all we know the software has arithmetic overflow or underflow when converting the a/d converter values into parts per thousand, it may have provable race conditions, dependencies on date/time or any one of dozens of typical software-only faults. Similar voltage-level dependencies could easily exist in the analogue circuitry - only a detailed design review by honest third parties can give good assurances to the contrary.

The fact that they won't hand the code over strongly suggest that it's never been quality audited or properly reviewed and may well indeed have dozens of stupid bugs in it.

I don't want to see drunken drivers get off, but neither should they be subject to randomness in their convictions.

Mike Banahan

Why aren't there consulting software engineers?

If you go into the civil engineering profession, there are consulting engineers who you can hire to keep your contractors honest. They'll watch the contractors like hawks to make sure they aren't cutting corners or stitching you up in other ways.

Software development is still in the dark ages on this - surely a large project like connecting for health should have a whole bunch of auditors and inspectors whose only job is to check that the contractors are doing what they were contracted to do?

Why doesn't the software industry yet have that kind of specialist at work?

Mike Banahan

True, it's only short range

As this web page convincingly points out, it's very limiting at these higher frequencies:

Low turnouts

In my business, if I don't deliver what the customers want, I starve or go bankrupt. I can't moan or berate my customers for being disinterested in my products.

It seems to me that politicians are in a uniquely privileged position and I'm unimpressed (I don't know an obscenity strong enough to really substitute for my diplomatic wording here) by their complaints about low turnout.

I have a solution: we know the going rate for the job of MP, Minister and so on. That rate should be paid to the incumbent pro-rata to the amount of the electorate that ACTUALLY VOTED for the lying cheating bastard. No, not the percentage that voted, the percentage of the registered electorate that actually voted for that person. So, if the PM's salary is a notional 150,000 or whatever and 40% of a 30% turnout voted for him, he gets 12% of the rate.

That's fair don't you think?

Mike Banahan

OMG

So the next aircraft to be brought down by terrorists will be caused by an undetectable and fairly hard-to-remove set of Bulgarian airbags that were stuffed with Semtex instead of the usual silicone or saline.

I seem to recollect reading that the largest implants favoured by exotic dancers run at about 1000 to 1500 cc, so that could potentially be 3Kg or more of high-explosive just waiting to cause mayhem.

I wonder how the security staff will check for that innovation?

Gobsmacked

I can't believe this is true. Although my period as a member of IST/41 (the BSI panel that is reviewing the fast-track document) was short, there was an air of intellectual honesty that gave me some modest pride being a part of it.

I really find it incomprehensible that the BSI panel might have changed its recommendation. The draft standard is truly, truly, appalling.

I will be fascinated to see if the rumor of a 5-1 change of mind is really true. If so, there will be a lot of explaining to do.

And I'd point out to anyone reading this that the panel is only advisory. If you feel that they have made a mistake, give the BSI a call on +44 (0)20 8996 9001 or email them at cservices@bsi-global.com

The ICT/-/1 (that's really its name) committee that actually decides the UK vote is only advised by IST/41, it doesn't have to abide by what they say. The BSI is supposed to work on consensus. If enough people call or contact it to tell it that it's made a mistake, it is supposed to do something about it.

If you care, get off your backside and tell them. I have already. Their vote is due in on the 29th. You have essentially one day only to influence them.
