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.

The heat of the action

In the evening, we watch gripping Nordic Noir episodes, and our spaniel sleeps soundly through the gunshots, stretched out on her big bed in front of the fireplace.

During the day, though, this kind of action will have her sitting alert and quivering with excitement at the patio door for hours!

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.

AirTags for Airheads?

Well, somewhat to my surprise, I found an Apple AirTag to be remarkably useful today! (I bought them because, well, I just like gadgets and these are beautifully-engineered gadgets, but I wasn’t sure how much I’d actually use them.)

This wasn’t anything dramatic: no long-lost pets being recovered from the other side of the county or anything like that. No, we were going out, and I wanted to find my keys. It turned out that, last night, I had used them to unlock the side door before putting some things in the recycling bin, and, perhaps because I had my hands full and my mind elsewhere, had left the keys on the shelf beside the door: not somewhere they would ever normally live. Then a plastic bag had been put in front of them, and they were hidden from view.

So it was no big deal; we would have found them again in a day or two, but the ability to track them down to roughly the right room and make them beep meant that we were out of the door a minute later, with no worries lurking in the back of my mind. It won’t take many such absent-minded moments on my part — and these are distressingly and increasingly frequent! — to make the tags well worth the money.

Getting 3-Dimensional

Some quick thoughts after my first couple of days of owning a 3D printer.

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!

Windowizer continued

I’ve had lots of fun comments about The Windowizer. People asked things like:

  • I like the Mac version – do you make one for Windows?
  • Where’s the Mute button?
  • Does it cut you off after 40 mins if you haven’t paid?
    and so on.

Amidst these customer support questions, I’ve been working on a conference-call version to help you communicate with groups of other people, but if there are more than about three or four participants, it becomes a lot less portable, because they also need some scaffolding to appear in the correct layout. Work needed there.

My friend Shaw also sent me this cartoon:

A think the spirit of Heath Robinson is still alive…

Marsh-wiggles

On the North Norfolk coast, you get these fabulous beaches.

Wonderful places to walk, though you may have to cover some distance at low tide if you actually want to see the sea! You can see how we had to fight our way through the crowds yesterday to find a space to launch the drone!

Between this beach and the car park, however, are salt marshes, which are also fascinating, and I’ve photographed them before, and more than once, from ground level. But the patterns and the scale start to become apparent when you can get a bit higher up.

That’s the path we took to walk out to the beach — the car park is where the brown meets the green — and it’s the path we should have taken to walk back.

(I’ve uploaded full-resolution photos too, so if you click on the pictures, you should be able to see rather more details, if your browser lets you zoom in. Can you see the bridge?)

We tried to find an alternative route back, an approach which had worked in the past here. But the marshes are always changing; you can think you’re almost at your destination, only to come suddenly upon a deep muddy trench that will give you no choice but to backtrack and lose the gains you’d made in the last 20 minutes.

It’s like a maze, but with more leaping. Don’t try it if the sun is going down!

There are some lovely spots where the marsh meets the beach.

But it’s the wiggly lines that I like the most.

You can perhaps see the same bridge in this picture: about three-quarters of the way up, in the middle. There used to be a couple more bridges over some of the tributaries, but I haven’t seen them on recent visits.

So I do wonder how the owners of those little boats get to them! At the moment, at least, what they’re sitting on is not nice dry sand, even if you can find your way there.

It’s a lovely and unusual spot.

Now, the real question is… who saw the title above and thought of Puddleglum?

How to change the default RSS feed reader on your Mac

This is one of those ‘in case you’re Googling for it’ posts.

On the Mac, it’s pretty easy to change the default browser, the default email program, and the app that gets fired up when you double-click on a particular file type in the Finder.

But when you’re in Safari and you click on a link to an RSS Feed, what happens then?

In my case, it starts up ‘Reeder’; a fine app, but not one I currently use, having switched to News Explorer a few years back. At some point in the past, I must have registered Reeder as my default news feed app, though I can’t remember whether the app did it directly; or whether I used the facilities in earlier versions of MacOS or a third-party app to make the association.

So how could I tell Safari (and the Mac more generally) that I now wanted RSS and Atom feeds to be handled by a different app? It’s not exposed in the settings of Safari, and not available in System Preferences.

Well, there used to be a utility called RCDefaultApp, and if you search for solutions to this problem, you’ll find many references to it. Unfortunately, it doesn’t work in recent MacOS versions due to changes in the support for Objective-C — the language in which it was written.

All of which is background information to the fact that Gregorio Litenstein has created a handy new Preference pane that allows you to change these mappings. It’s written in the Swift language, and so is called SwiftDefaultApps.

If you have Homebrew installed, you can get it easily with

brew install --cask swiftdefaultappsprefpane

Otherwise, you can install it following instructions on the site.

It then appears at the bottom of System Preferences, and in my case:

  • I went into the Internet tab and changed the RSS setting to point to NewsExplorer, and then
  • I went into the URI Schemes tab, added an entry for ‘feed’, and set that to point to NewsExplorer.

Sure enough, when I now click on an RSS link, Safari asks if I want to open it in News Explorer, and all is well!

(Note that this is a system-wide setting, but other browsers may not use it; Firefox has its own way of setting up such apps, for example.)

Anyway, if you’re trying this, you probably want an RSS link to test it on, and you’ll find that there’s a convenient one at the top right of this page… 🙂

The search for warmth

Here’s a nice story on the BBC. I had never really thought about the value of drones for search and rescue, but on the River Foyle they have one equipped with a thermal camera, which can really help find people in the river, especially at night.
