It only takes one bit of data…

A few days ago, I created a new Facebook account. Not for myself, of course; I’m not stupid! (I deleted my own account many years ago and haven’t looked back.) No, it was because my company was writing some software that connected to Instagram, and doing that requires you to have a Facebook account in order to get ‘Developer’ access and for testing.

So, I set up a new email address and registered with a somewhat fake name, logged in and started browsing a generic here-are-some-feeds-you-might-be-interested-in type of experience. No personal details… all nice and anonymous.

The following day, I couldn’t log in. “Your account has been blocked.” Had I been rumbled? Ah, no, they just wanted to check I was really a real human by sending a text to my phone. I put in my phone number, got the text, filled in the code, and I was back in again. Jolly good. I logged out and went back to work.

A few days later…

The following Tuesday I logged in again, and there was a picture of my cousin, listed as someone I might want to connect with. Nice picture, I thought. And then, “Wait a minute! How do they know about her?”

I scrolled down, and sure enough, there were my friends, family, past work colleagues… dozens of ’em, all just waiting to welcome my ‘anonymous’ account into the fold. And then I remembered…

I still have a WhatsApp account. I seldom use that, either, but it’s there. And so, I presume, the act of entering my phone number for a security confirmation on my test account gave Facebook access to my entire graph of social contacts. Or, and perhaps in addition, lots of people with Facebook apps on their phone will have my phone number in their contacts. Facebook know exactly who I am, and all about me. Sigh. Should have used a ‘burner’ phone! Meanwhile, my friends have probably all received invitations to befriend a strangely-named new account and thought that the Facebook algorithms had gone a bit squiffy. Oh no. They’re working perfectly.

There is, however, something that still intrigues me. A noticeable aspect of the front page was the range of dog-related material. If this came from WhatsApp, how did they know I liked dogs? I guess it might be an Instagram link, but I really don’t have many dog pictures there either. Mmm.

No, I suspect this must be because I used my spaniel Tilly as the profile pic on the company account, just for fun. (Her modelling fees are very reasonable, and can be paid entirely in Bonios.) Anyway, if that is how they made the connection, then I can’t help wondering what other analysis they might be doing of people’s profile photos…?

Of course, I thought, I may be imagining it; they may just have decided that dogs were a cute and safe bet for the populace as a whole.

But I notice that there weren’t any pictures of cats on my page.

The Alpine Butterfly Knot

As someone who has done a fair amount of sailing in my youth, I like to think I’m more familiar with knots than the average bear. But there was one that I’d heard of in the past but knew little about: the Alpine Butterfly Knot (or Loop). It looks like this:

and it turns out to be jolly useful, but if you just look at it, it’s very tricky to work out how to tie it quickly.

There are lots of different techniques and lots of different YouTube videos about them, but today I found the method I liked the best:

Important YouTube Changes

In October, I wrote about my enjoyment of and use of YouTube, but I predicted that, at some point, people might want to shift some of their content elsewhere.

Well, that hasn’t happened yet, but there’s a small step today which might make people think more about it: the new Terms of Service, which take effect on 1st June. These include the following:

Right to Monetize

You grant to YouTube the right to monetize your Content on the Service (and such monetization may include displaying ads on or within Content or charging users a fee for access). This Agreement does not entitle you to any payments. Starting June 1, 2021, any payments you may be entitled to receive from YouTube under any other agreement between you and YouTube (including for example payments under the YouTube Partner Program, Channel memberships or Super Chat) will be treated as royalties.

Now, for most viewers, this won’t make much difference. We’re used to seeing ads on YouTube videos; in fact, quite a few of mine have them, and I earn enough from the ads to keep me in coffee beans. (I only use skippable ads at the start of the video, since I think those are the least annoying. You get more money if you allow others.).

When you view a YouTube video with ads, the revenue is typically split between YouTube and the creator. This revenue-sharing partnership is available to creators who have enough followers and sufficient viewing hours. In some circumstances, if you’ve included other material (such as commercial background music for which you don’t have a licence), rather than blocking you completely, YouTube will allow it to be posted, but you can’t monetise it: ad revenues are shared with the music copyright owner instead. The 360-degree video I recorded of my campervan trip to the Dordogne is an example: it does have ads, and the proceeds go to the creators of the background music I occasionally include. That seems reasonably fair to me. Doing this does have risks, though, if you’re thinking of trying it: firstly, you need to check whether it’ll be allowed for the tracks you’re thinking of including, and secondly, if the music publisher changes their policy in the future, your video may be removed.

Anyway, this new change will allow YouTube to put ads on the videos where I haven’t enabled them, perhaps to include more of them, or different types, and not necessarily share the proceeds of these extra ones with me. What’s more, if I had a very popular video, I think they could decide to put it behind a paywall.

As well as being detrimental to the viewing experience, this could be important, say, for universities who don’t want advertisements on their lectures, or software developers who don’t want competitor’s ads popping up over their tutorials. There will be ways around this, no doubt, involving payments to YouTube.

But this is just a reminder to make sure you keep copies of all the videos you upload in preparation for the day when you might want to move them somewhere else because your friends and family can’t watch them without a YouTube subscription.

YouTube is an amazing service, and a phenomenally expensive one to run, and most of us get it for free. So the fact that they are always looking for extra sources of revenue should come as no surprise. Especially to readers of Status-Q!

The uncomfortable truth about tithes

Many religions, especially those with Mosaic/Abrahamic connections, embrace the concept of ‘tithing’: giving one tenth of your income to the church. Originally, of course, this referred primarily to agricultural produce; in more recent years it tends to focus on Standing Orders and Gift Aid. Jesus himself apparently said little or nothing about it, which has allowed different groups of his followers to put differing degrees of emphasis, or compulsion, on on the concept since. But it is, of course, generally regarded by church leaders as desirable, and in my youth, sermons pointing out the biblical distinction between ‘tithes and offerings’ were not uncommon — the former being expected and, in effect, already belonging to God; the additional voluntary contributions constituting virtue (as long as both were done in secret).

Over coffee, after one of these sermons, I sympathised with the preacher. How obvious it was, I said, that very few people took these biblical directives to heart. He made some remark about how he was fortunate to have a generous congregation, and I fear I may have emitted something like a snort as I looked around at the gathered multitudes. I was very fond of them too, and many of them were very generous people, but I pointed out the mathematics…

In the Anglican church, for example, if people took tithing seriously, then every nine parishioners could support one vicar, who would then have the same average standard of living as his flock. (That got his attention!) You would need ten in your congregation if the vicar tithed too (which I guess would allow ten vicars to support one bishop, and so on).

OK, and you have to maintain the church buildings, do some good works, etc. So perhaps you need a congregation of about 15 people per priest for the church and clergy to lead a comfortable life. (That’s assuming your church doesn’t have any other income from land, bequests, indulgences or whatever…)

In the 35 or so years since that conversation, church attendance has declined so rapidly that many parishes will be doing this kind of maths for themselves. The average C of E congregation is something like 30-40 at present. But back then, though, I fear I may have left him contemplating his congregation of around 150 a bit less favourably than when he started his mug of coffee.

Location, location, location (or, ‘How technology saved me a few hundred quid yesterday’)

Yesterday, I lost my glasses. This is perfectly normal, and happens on a regular basis. One of my roles in life is to provide the opticians of South Cambridgeshire with a healthy and predictable revenue stream. What was much less typical about yesterday, though, was that I found them again!

Despite some of my recent posts, this was nothing to do with Apple AirTags, because I don’t currently have those attached to my spectacles. (I thought I looked rather dashing with them dangling about the ears, and many of the chaps at the Drones agreed, but I noticed that Jeeves had become particularly frosty recently, and found himself unable to extract me from a dashed sticky situation involving Madeline Bassett… but I digress. No AirTags currently adorn your correspondent’s brow.)

Anyway, yesterday afternoon, I was out walking Tilly, in a gentle rain, and I decided to take a photo of the view across the field in the mist. “This shot would be easier to compose”, I thought, “if I were wearing my glasses”, and I reached into the pocket of my coat… to discover that they weren’t there.

“Bother!”, said I, contemplating the last couple of miles that we had walked, the branches I had ducked under and the ditches I had leaped, any of which might be clues to their likely location. But then I remembered I’d received a phone call just a few hundred meters back, and had been able to read the name of the caller with ease, so I must have been wearing them then. I started to retrace my steps, gazing without much hope at the long wet grass, and thinking how easy this would have been if it weren’t for Jeeves.

After a couple of further passes over the relevant stretch, in the fading light, with a bemused (but useless) scent-hound trotting behind, I was about to give up hope, when I suddenly remembered: Hang on a minute! I had taken one other photo! It was after the call, but before I had noticed the glasses were missing. Surely I must have been wearing them then, and removed them afterwards because of the raindrops gathering on them. I bet I dropped the glasses at the location of the photo!

The problem was that it hadn’t really been a great photo; not many distinguishing features in the view. I was along one side of a big field, on a wide path, and I had paid little attention to my surroundings. Looking back at it now, I realise that I could probably have got those two rows of distant trees in the same relative alignment and located my former position quite accurately, but I was trying to view it on a small and decidedly damp screen… without my glasses. I was having enough fun just trying to tap on the right photo.

However, of course, all my photos are geotagged. I spent a while trying to work out how to see its location in the Photos app: not easy, even when you can read the text and make out the icons. (Hint: you need to swipe up from the bottom.) But eventually I found it. Not entirely helpful for precise location.

By tapping random blurry things, I managed to get into satellite view, and that was much better:

However, you have to remember that, at the time, it looked more like this:

And there are quite a lot of bends in the path with big trees beside them.

The Photos app doesn’t show your current location, only the location of the photo. I switched into Google maps, where I could see the moving blue dot, but the trees and crops looked completely different; the photo had been taken at a different time of year, several years before. Not much help.

But Apple Maps, of course, used the same satellite imagery as Apple Photos, and I was able to switch to and fro between the apps as I walked, until the blurry image with a blue dot seemed perfectly aligned with the blurry image with a yellow square.

I looked down, and there, nestled in a tuft of long grass, were my glasses. I had passed them three times that afternoon since dropping them, as had Tilly, who can track a pheasant at a considerable distance, but takes little notice of her master’s most valuable possessions right under her nose.

“At last!”, said she. “Come on! It’s dinner time.” And we scampered off towards the car.

Unwanted Corkpull

This is a lovely essay by Kelly Pendergast, brought to my attention by Andrew Curry on his Just Two Things newsletter.

It’s beautifully written and an enjoyable read, which is quite an achievement when it’s talking about consumerism, supply chains and waste management. Don’t let that put you off. Lots of good stuff there.

She talks about the admirable Oxo corkscrew she was given by a friend.

I suppose I should be happy to own such a perfectly functional piece, no muss, no fuss, no danger of injury, but what can I say? It’s ugly and I don’t like it.

You may not be surprised to hear that it was a gift. Life would be simpler if it had never entered the house, but between the gift-ness and its unfortunate excellence at performing its single task, I haven’t been able to get rid of it. Marcel Mauss, in his inquiry into the anthropology of the gift, asks “What power resides in the object given that causes its recipient to pay it back?” The gift corkscrew is freighted with a psychic weight that can’t be directly repaid, but can’t be forgotten.

She includes a memorable quote from Robin Nagle, anthropologist of material cultures and anthropologist-in-residence at the New York Department of Sanitation. (Now, that’s a job title to conjure with!)

“Every single thing you see is future trash.”

She talks about the other kinds of emotional weight we attach to objects, (or, sometimes, don’t, when we should do), and a feeling of guilt about being part of the flow of manufactured items on the way from raw materials to the grave…

Anyway, as Andrew Curry said, it’s hard to do it justice in excerpts; just read and enjoy.

On that topic, having referred to my late friend Martin King a couple of days ago, I will do so again today.

I remember that we were buying furniture for one of our companies’ offices, and he was spending some time seeking out used, good-quality, basic tables and chairs, which also seemed rather expensive to me. I probably said something about it being easier and cheaper to get them from Ikea.

“Yes”, said Martin (who, despite his considerable wealth, generally shunned anything that looked like luxury), “but we buy quality things because we don’t want to be responsible for creating rubbish in the world.”

That was a phrase that stuck with me.

Understanding the rules of the business game

I was once out for a walk with a friend who had also been a major investor in one of my startups. I bought her a cup of coffee and she said, “Oh, let me pay for that!” and I responded with, “Don’t worry, I owe you about a million quid anyway”. She laughed, but I know she remembered it.

And so did I, because afterwards I realised I was wrong. I had fallen into a common trap: an assumption that those who receive money should necessarily always be grateful and subservient to those who provide it. In one sense, those who are on the receiving end are naturally inclined to feel that way, because without it, our business, our grand plan, our pet idea, wouldn’t survive. In the short term, we need them more than they need us. But (except in very rare circumstances) it’s a deal, not a donation. Investors in startup companies are not just doing it out of the goodness of their hearts; you are giving them something in return; they are, in a very real sense, paying for your services, in the hope that everybody will make a profit out of it (and probably them much more than you). What I should have added, to my investor friend, is something along the lines of, “I owe you about a million quid, but I guess you owe me and several of my friends many years of our lives, so perhaps we’re quits.”

This is true of employment, too. For those of us fortunate enough to be in the Western tech world in a period of high employment, we’re making the same deal: you’re giving me money, I’m giving you a certain fraction of my life. This is not a master-slave relationship, it’s a barter relationship, and if either side doesn’t like the deal, they can go elsewhere or (increasingly) set up in business on their own. I appreciate that this is an historical, geographical, and industrial anomaly, or at least novelty, so please don’t send me emails about the Tolpuddle Martyrs! (Been there, seen the tree.) But it’s the world many of us are fortunate enough to live in now. The them-versus-us tribalism of management and workers in the industrial revolution, or in the 1970s and 80s, is no more helpful in the 21st-century tech business, or the 21st-century gig economy, than it is in 21st-century Facebook-exaggerated politics.

Thinking about this reminds me of a conversation in a Seattle cafe with my late friend Martin King, when he was asserting that there was no reason companies should not have the same ethics as, and be as nice as, individual people. (He was referring to their dealings with other companies, more than employee relations.) I applauded his intentions (and tried to follow them myself to a significant degree).

However, I pointed out, there was a fundamental difference between business and personal relations: business is inherently competitive. It’s more like a sport than a social function, and you need to understand the rules from the word go. Imagine if you entered what you thought was a garden party, and it turned out you were in rugby match, or a boxing ring. Human interactions work if everybody inside, say, the boxing ring, knows the rules and plays according to them, but they are different from the rules of normal social engagement.

The relationship between a company and its employees, of course, is not, one hopes, competitive in the same way, but it is still a business deal, a game played according to certain rules. This is why the recent attempt by the founders of Basecamp to clarify the rules of their game was, I think, both admirable and controversial: their rules seem very sensible to me, but some people thought they were playing a different game (or wanted to) and so departed for another playing field. Sometimes, yes, the rules need changing. Sometimes they need clarifying. Sometimes they should have been clarified earlier. But sometimes you’re just on the wrong playing field!

So make sure you understand the rules of the game you’re playing. If you’re accepting money from an investor, remember that they’re doing it because they expect to get at least as much from you in return. If you’re earning easy money as a driver because you installed an Uber app (rather than having to apply for a traditional job with an employment contract), be aware of the nature of the relationship and don’t complain because you later decided you wanted something different. And if you should happen to wander into a boxing ring thinking it was tea at the vicar’s, don’t be surprised if what you get in your mouth isn’t a cucumber sandwich. This is a fault in your research and your expectations, and not necessarily in those of the person delivering the surprise!

Once you know which playing field you’re on, of course, you should then be a good sport to the best of your abilities! And so should companies.

Covid: Destiny and Density?

It always seemed probable to me that Covid infection rates would be closely related to population density. When you walk down the street, how many people do you pass? Are you in a house surrounded by fields or in a tall vertical apartment block where you share an entrance and staircase with many other households? How big are the schools? And so on.

At a country level, though, this is difficult to test. I plotted the very latest total number of Covid-related deaths per million population against the population density per sq. km. for some countries similar to my own (UK), and it didn’t show a clear correlation.

Sources: Statista and Wikipedia.

(As usual, whatever they’re doing in the Netherlands is good. Why do the Netherlands keep doing that with everything? Please stop. It’s very annoying to the rest of us.)

Depending on your political persuasions, or whether you’re a glass-half-full or a glass-half-empty kind of person, you could interpret this in various ways!

My own view (at present), for what it’s worth, is that our government and senior civil servants didn’t put enough emphasis on lockdowns in the early months, and that cost us a lot. But they did put much more energy and resources than most other countries into securing vaccines on a huge scale, very early, and we’re now reaping the benefits. So depending on the time period you examine over the last year, the picture relative to other countries can look very different. (The sadly-missed Hans Rosling would have had some nice animations, no doubt!)

At present, if you take the long view of total Covid deaths per capita, we’re a bit higher than the average for similar countries, but our rate of new deaths is lower than almost anyone’s, so we will probably look better over time. So it could have been much better, and it also could have been much worse.

Anyway, back to population density. The problem is that density is far from evenly distributed. If I plot England on the map, as distinct from the UK as a whole, it appears in a very different place: the top-right:

England is up there with the most-afflicted other countries from my list — Italy and Belgium — but it does have a notably higher population density than any of them.

Anyway, the results of my quick graphs are that I was probably wrong: it’s not clear that population density is a useful metric, at least when done at this scale.

What we really need, if we want to compare the situation in different countries, I think, is statistics about both Covid cases and population density across Europe on a 20km grid. Then we could compare them more usefully, and one day, perhaps, we’ll know whether I’m wrong in the details too, or only on the larger scale!

Street View Statistics

Google Street View is, I think, one of the most amazing achievements in recent times, and it’s one of the things that keeps me using Google Maps even though many of the alternatives are rather good. If I’m heading to a new destination, I’ll often look in advance at, say, the entrance gate, or the correct exit from the last roundabout, so those final manoeuvres when the traffic is slowing down behind you are less stressful: you’re in familiar surroundings. Street View is, in that sense, a déjà-vu-generator.

And of course, it’s great for bringing back memories of places * qu’on a vraiment déjà vu*. We can all think of dozens of examples; for me, this morning, the sea front by the Ullapool ferry terminal is somewhere I remember as a launching point into the unknown; it’s where I stayed at a lovely inn before catching the ferry to the Outer Hebrides. Happy memories.

But there are interesting questions to be asked about Street View as well. For someone who enjoys window-shopping on Rightmove for a possible next home, it’s a very valuable tool, and I’ve often wondered how much the market appeal of your property is affected by whether the Google car drove by on a sunny or a cloudy day!

And this morning, I saw debates on Twitter about research that used images of your house on Street View to estimate how likely you were to have a car accident, something which could be used against you by insurance companies (or, of course, in your favour, but that doesn’t make such good headlines).

The paper’s here, and I was most surprised by just how poor the insurance company’s existing model was; information about your age, gender, postcode etc apparently doesn’t give them as much insight as you might expect, and knowing whether you live in a well-maintained detached house in a nice neighbourhood gives them just a little bit more. Some see this as very sinister, but you need to remember that this wasn’t some automated image-analysis system; the researchers had to spend a lot of time looking at StreetView pictures of houses and annotating them by hand with their assessment of the condition, type of house, etc. Some of this could be performed by machines in future, but there are lots of other factors to consider as well: is the issue that you are more likely to crash into somebody in certain neighbourhoods, or that they are more likely to crash into you? What’s the speed limit on the surrounding streets? How close is the pub? And so on…

So I sat down thinking I would write about this, but one thing I failed to notice was the date of the research. I assumed that because people were talking about it on Twitter today, it must be new — a fatal mistake. What’s more, just a little bit of further research showed me that my friend John Naughton had written a good piece about it in the Observer two years ago.

So it’s perhaps not surprising that I like technologies that can give me a sense of déja vu. My own abilities in that area are clearly lacking!

A family memory of the Duke of Edinburgh

My late aunt Margaret (always known to us as ‘Auntie Peg’, and of whom I was exceedingly fond) welcomes the Queen and Prince Philip on a visit to Bombay.

I never met my uncle James (behind in white), but he was Deputy High Commissioner from 1960-63, and the royals stayed with them for a few days as part of their extensive tour of India and Pakistan in 1961.

Covid Conveniences

During the lockdown last year, when things began to open up a bit and we could go for outings to Norfolk beaches and other somewhat distant spots, there was always, lurking in the background, a rather practical matter to be considered: what happens if you need to go to the loo when you get there? With cafes, pubs, shopping centres and many other public locations closed, this could be an issue if you were visiting a remote location. A day trip and picnic was a delightful Covid-safe affair, but one didn’t want it to be overshadowed by such… shall we say… immediate concerns.

Well, back then, we had no problems, because we owned a small campervan, which included the necessary facilities. Now, however, we’re in the same situation but without such a vehicle, and need to consider such things more carefully.

Supermarkets are often a good spot to visit when on a long journey: plentiful, open for long hours, and trivial to find and insert into your route with just a couple of taps on Google Maps. On long drives through France in pre-lockdown times, there were many big stores at which I made small purchases! (It is worth noting, though, that this strategy will let you down, at least in the UK, if you have chosen Christmas Day or Easter Sunday for your outing, as we recently discovered!)

I wouldn’t want anyone to think I was obsessed with this subject, but I was a Cub Scout once, so I like to Be Prepared, and we blokes can often underestimate the challenges faced by the ladies. There are also many people, of course, for whom medical or other conditions make this a more serious issue. A useful, but not widely-known, resource in the UK is The Great British Public Toilet Map. Or perhaps it is widely-known, but not widely discussed in polite company!

As an aside, one of the jobs of art, occasionally, is to ask challenging questions of polite company, and it’s hard not to be intrigued by Monica Bonvicini’s installations in London and Basel some years ago, entitled “Don’t Miss A Sec”, which must be the ultimate use of one-way mirrors.

But I digress. This is an issue that has followed us through the ages; is there any hope of relief in the future? Well, looking back at past Status-Q posts from a couple of years ago, I remembered that an acquaintance and I had spotted a real business opportunity. I wonder if anyone will get around to commercialising it before the next pandemic…

Lockdown listening

“I don’t really listen to many podcasts now…”, I heard someone say recently, “…because I no longer have a commute”. This made me realise how different my listening habits would be if I didn’t have a spaniel to walk. (I’ve tried the commuting thing on occasion, by the way, and gave it up as a bad lot. Spaniels are better.)

I tend to listen to a mix of podcasts, but they are mostly tech-related. There are shows like Self-Hosted and 2.5 Admins if I want to know which hard disks to put in my NAS, when to use FreeBSD instead of Linux, or how to back up my ZFS filesystems. I enjoy Clockwise for a light-hearted quick-fire discussion of tech topics and gadgets, and, almost at the opposite extreme, the State of the Net podcast is a gentle, contemplative and insightful chat about broader issues. There are some which cater to my more particular interests, like the Home Assistant podcast (about my favourite home-automation system) and the Fully Charged podcast (about EVs and renewable energy). And then, for something completely different, the Talking Politics History of Ideas educates me on the work of MacKinninnon and Marx, of Wittgenstein and Wollstonecraft.

But brief podcast episodes are interspersed with much longer audiobooks, and it’s no exaggeration to say that our Audible subscription is one of the best services we have, in terms of the number of hours of enjoyment per buck. My wife Rose could never be persuaded to carry a smartphone anywhere, until she discovered it could read all of her favourite books to her, and now it goes everywhere. She’s never used any other iPhone app, and almost never used it as a phone. She has taken some photos over the years – but probably less than a dozen! No, for her it is first and foremost an audiobook player, which can be used as a phone in an emergency.

We aren’t, by the way, walking around with headphones on all the time. The iPhone speaker is fine for most of our normal use, if placed in an appropriate pocket. And we enjoy many of the same authors, so snatches of Conan Doyle, of Nevil Shute, or of Tolkien can often be heard from any corner of the house. In unabridged form, of course.

We both share the same favourite modern author — Patrick O’Brian — and the audiobooks, beautifully read by Ric Jerrom, are quite superb. If you’ve never tried audiobooks as an accompaniment to your walking, cooking or ironing, start with Master and Commander, and you can be assured of many, many happy hours.

Especially if you also have a spaniel.
