With great power…

Back in the early days of USB, my friend Andy Fisher and I were bemoaning some of its design flaws as a communication system.  “But”, he pointed out, “USB is the first universal power standard”.   I laughed, and agreed. People didn’t really think of USB as a power source very much then, so this was an interesting observation.  

Andy and I were doing a lot of flying to places with different mains power standards, and we had phones from people like Nokia and Motorola, so we had to carry lots of chargers with a wide range of connectors and adaptors everywhere we went.  The idea of a predictable socket giving you predictable power was very appealing, even if it was only 5V at 1A. (Though I later realised there was perhaps one earlier holder of the ‘universal power standard’ title: the car cigarette-lighter socket.)

Screenshot 2023 09 21 at 09 38 18This week the news is full of the fact that Apple are switching the iPhone to use USB-C.  This is assumed to be largely the result of EU directives compelling them to do so, but my latest iPad and laptop from them are already USB-C, so it was probably inevitable anyway.  Personally, the ‘Lightning’ cable has always worked very well for me; I’ve never had one fail and on the rare occasions when I plug it in my phone and it doesn’t charge, the solution is invariably to remove the pocket-fluff in the socket (which, by the way, is best done with a wooden cocktail stick).  So for many people, whether you approve of the change probably depends on whether you have bought lots of Lightning-based accessories in the past, and how that balances for you against not having to do so in the future!

USB-C, on the higher-end phones, will give much faster transfer rates, which is important for those copying substantial video clips to their laptops, but probably irrelevant for most other people.  And USB cables can be highly confusing, because you can run other protocols over them alongside the USB communications; DisplayPort being a key example, but also including things like Thunderbolt and PCI Express.  When you plug a cable between two USB-C sockets, therefore, it can be hard to know what you’ll actually achieve: the projector in this meeting room has a USB-C socket, but will that allow me to display my presentation or just charge the remote control?  Might it even recharge my laptop for me?  Make sure you try it in advance, because you can’t tell from the sockets, and it may also depend on the quality of cable you use to connect them.  Plugging things together will almost certainly be a safe operation, but it may be a disappointing one.

Sometimes, though, you can get a pleasant surprise.  I remember when I wanted to connect a small stick-type computer to my monitor, and plugged in a USB-C cable to provide the DisplayPort video connection, only to find the computer booting up because the monitor was also able to power it, through that same single cable.

And while I still regularly complain about USB in general — I have two or three hubs on my desk to connect all my peripherals, from reputable manufacturers, yet I regularly get messages about some external drive being improperly disconnected, or find some camera needs unplugging and replugging before it appears in Zoom —  I do have to admit that USB-C, at least from the ‘universal power standard’ viewpoint, does seem to work rather well, so I’m in favour of this change for technical reasons, as well as environmental ones.

If you want to know more about USB-C power, what it can do and how it does it, I recommend this Hackaday article by Arya Voronova.  He points out that there are still some issues — if you plug your battery power pack into your laptop, for example, do you expect the laptop to charge the battery, or the other way around? — but overall, it does seem like progress.

The shelf behind me in my study has three large boxes labelled ‘Power Supplies < 12V’, ‘Power Supplies 12V’ and ‘Power Supplies >12v’, because I always hated throwing them away.  In the past, power supplies generally died more regularly than the things they were powering, and it was very satisfying to be able to reach into one of these boxes and give a computer, drive enclosure or ethernet switch a new lease of life.

But I think it may be time for a clear-out.

PSU boxes

I now have a reasonable number of adaptors to connect USB-A to USB-C sockets and vice versa, and this should work in most simple cases. But you’ll get the lowest common denominator of the two standards, which may not be enough. Just last week, I was installing a new phone mount in my campervan; one that would hold my phone in place magnetically and charge it wirelessly. The Magsafe wireless charger came with a USB-C cable and I just plugged it, via an adaptor into to the USB socket on my dashboard. But… Nada. It turns out that the wireless charger needs more power than a standard USB-A socket can provide. I did actually need to plug it into USB-C.

Fortunately, that was easy to solve. Because my dashboard is also fitted with the original universal power standard. A cigarette lighter socket.

Drug-inspired Lyrics

I know that many popular lyrics have been inspired by the use of drugs, so I thought I’d try my hand at it.  This was written recently while packing for a journey.  Or, perhaps, a trip.  My brother, a highly-qualified medic, was on hand to help. With the lyrics, at least.

John and Yoko are busy composing the melody, but in the meantime you can sing it to the tune of It’s a long way to Tipperary.

I need one more Atorvastatin
  I’ve got one more to go.
I need one more Atorvastatin
  It’s the neatest pill I know.
Goodbye to cholesterol
  Farewell, LDL!
I need just one more Atorvastatin
  And all will be well!

I expect it to become a hit amongst other middle-aged music afficionados.

Boom or bust

When I was writing recently about ‘generations’ and ‘Baby-boomers’, I came across an interesting article talking about why the Baby Boom happened. It wasn’t just those soldiers coming back from the Second World War and making up for lost time, because it started in the 1930s. Interesting reading. Part of the motivation for the article, though, is that if we could understand why sudden changes in fertility rates happened, it might help reverse the current decline in birth rates.

This is something I have never understood.

Surely, the best thing we can do for the planet, and for the generations who will follow us, is to encourage declining birth rates wherever possible. Nobody likes to talk about it — it’s certainly not a vote-winner for politicians — but the single best way for a couple to reduce their carbon footprint is to have fewer children. If they can instil that tendency in any children they do have, too, their decision could have an exponential long-term impact through time. Forget installing solar panels or buying an EV! Spend the money on contraceptives if you really care about climate change. A world with less congestion, less competition for resources, less overcrowding, less pollution, less demand for housing, less intensive farming… can only be a better world, it seems to me?

We should institute tax benefits right now for people with fewer children, rather than continuing child-support for those who breed excessively. Those who install solar panels, drive Teslas and, most of all, are voluntarily childless, should of course be publicly honoured and cheered in the streets. (I may have a slight personal agenda here!)

Seriously, though… I know there are issues with an ageing population. Declining birth rates mean more old people hanging around for younger people to support. (Though in a country with a good social security scheme, that larger elderly population should at least have paid for most of their care up front during their working lives.) A declining birth rate also tends to lead to reduced economic growth and a few other challenges.

But it’s always seemed to me that these are short term problems, and somewhat selfish arguments. Yes, our modest numbers of children, grandchildren and perhaps great-grandchildren may not appreciate the demographic change until we’re well out of the way. But for those with a longer-term view, won’t the denizens of the 23rd Century be exceedingly grateful for anything we can do now to encourage population decline? And isn’t that the best way to ensure there will actually still be people around to enjoy the 24th Century?

Posting for Posterity

I’ve written before (e.g. in May) about the importance of the Internet Archive, which I was fortunate enough to visit in its early days. It’s a hugely valuable resource for many reasons, not least in giving some protection against link rot through its ‘Wayback Machine‘.

What I’m embarrassed to say I didn’t know until recently, or had forgotten, is that there is also a UK Web Archive at webarchive.org.uk . It’s a very nicely-done collaborative project of the UK Legal Deposit Libraries, and performs a similar task for UK-based websites.

It’s been going for 10 years now, which is a good span but not nearly as long as the Internet Archive, so if, say, you were feeling gloomy about the situation in the UK and needed to be cheered up, you could go and look at the old News of The World site and be grateful that it ceased to exist 12 years ago.  For that, though, you would need to go to the Internet Archive.

The UKWA is a great initiative,and worth supporting. If you have a UK-based site which isn’t already indexed, let them know. It’s another good way to try and ensure it outlives you, and they try to update their copy at least annually.

And if you want to know more about the UK’s Legal Deposit Libraries which are behind the project, Tom Scott (of course) has a nice new video.  

 

Generation game

I hear these phrases like ‘Millennials’ and ‘Generation Y’ in the media and realise I have no idea what they mean. Perhaps it’s because I don’t have kids, and so don’t know which pigeonhole the tabloids and marketing agencies want them to occupy!

I know roughly when ‘baby-boomers’ were born, but that was a phrase invented in the seventies to describe a genuine phenomenon visible in historical data. And I presume ‘millennials’ are people born around the turn of the millennium. But when did it become trendy to label other generations? And who decides on the boundaries and the letters? (I suspect the culprits are the same people who tell us that this is “International Year of the Aubergine“ and things like that.)

I have no more idea of which ‘generation’ I fall into than I do about my supposed star sign, and I suspect they are almost equally fictitious constructs. I’m guessing someone invented ‘Generation X’ because, while it was easy to say ‘grew up in the fifties’, it’s just too silly to say ‘born in the noughties’ (or whatever Generation X actually means). We really don’t have very good words for the last couple of decades. It’ll be easier in a little while when we can talk about a ‘twenties kid’. And if (as I assume), Gen X and Y (and I think there’s even a Z now) all came after Millennials, then they can’t really be generations, can they? There’s not enough time for them to have 20-30 years each… At least they’ve run out of alphabet now, so perhaps they’ll need to start using some meaningful names again soon.

Still, I was distressed to see the single-letter-generation-labelling game going on even in reputable newspapers recently, so I’d better go and find out what they’re supposed to mean, and what unicode character they’re going to adopt for my great-nephews/nieces expected in the spring. Perhaps it’ll be an emoji. I like to think they’ll be part of ‘Generation 😁’.

Yes, I’d better go and look it up. Otherwise I risk being relegated to that no-man’s land of the ‘post-boomer-pre-wikipedias’…

Ottery St Mary

We were passing Ottery St Mary, Devon, on our travels, and were pleased to see a sign to a pottery. Yes, there’s a pottery in Ottery. I started to consider its likely back-story…

There once was a lady from Ottery
St Mary, devoted to pottery.
If she saw a vase,
Wherever she was,
She’d say, “In my collection that’s gotta be!”

Well… you don’t expect anything too deep while I’m on holiday, I hope?

I like to think that the pleasing name comes from there being a lot of otters around, so making the area particularly ottery, but in fact the town lies on the River Otter. Confusingly, there’s also a River Ottery in Cornwall, but I can’t discover that either waterway is particularly known for its otters… in fact, the River Otter, according to Wikipedia, is unusual in having the UK’s only known breeding population of beavers.

They probably settled there just to confuse people.

Watching the clock

I’ve written several times about my enthusiasm for the Apple Watch, but even eight years after getting my first one, I’m still discovering uses for it.

We’ve spent the last few nights in our campervan on a delightful small campsite in Devon.

Picture of campervan in a bucolic setting

There are loo and shower facilities in a nearby building but, unusually these days, you do need to insert a pound coin if you want to use the shower. It’s a fine shower, and I didn’t mind paying, but since the meter is outside in the corridor, you don’t get any warning before the water shuts off suddenly after six minutes, possibly leaving you rather soapy…

So even in this low-tech environment, where we treat an electricity supply as something of a luxury, there’s great benefit to be derived from a waterproof watch which can be instructed, with a couple of clicks or a spoken command, to warn you shortly before your shower is going to finish!

Maiden Voyage

We have a new toy: an inflatable kayak. We had one of these before and had loved the versatility: you can launch them almost anywhere. But the one we had was really designed for white water and surf… not much call for those in the East Anglian fens, where something that travels longer distances in a straight line was more desirable!

Regular readers will know that we also have a little sailing dinghy and another inflatable which we use with an electric outboard. So you might well consider that three boats for two people is a bit excessive! But they all have different roles, and there’s something delightful about getting on the water in something that needs as few accessories as this does.

Some are more equal than others

“Not all cottons are equal”, says the label on my new John Lewis shirt. “We use Supima cotton because it’s one of the most superior types of cotton in the world for creating strong, comfortable and colourful fabric.”

Oh, for heaven’s sake! One of the most superior types in the world? What do they teach kids in English lessons these days? Before you ask, this does appear to be a label printed by that old English retail partnership itself, not by the Bangladeshi factory from which the shirt originates.

Still, perhaps I’m being too fussy. At least they are only claiming it to be one of the most superior types, and, in any case, if I am going to wear a superior type of cotton, I should probably be grateful that it’s not one of the least superior types.

Abandoning my principles

Two quotations occurred to me this morning.  The first was from Edmund Blackadder, talking to Prince George:

“Well, it is so often the way, sir: too late one thinks of what one should have said.

Sir Thomas More, for instance — burned alive for refusing to recant his Catholicism — must have been kicking himself, as the flames licked higher, that it never occurred to him to say, “I recant my Catholicism.”

Leaving aside for a moment a somewhat rare error on the part of the writers — Thomas More was beheaded, not burned — the topic of when to abandon one’s principles was in my mind, because I was reinstalling WhatsApp on my phone, having deleted it several years ago.

I have written enough here in the past about why I consider Facebook not to be a force for good in the world, and why I think that all of their apps — Facebook, WhatsApp, Instagram, and now presumably Threads — go a step too far in the privacy-infringement arena because, for example, they capture the details not only of the person using the app, but of all their contacts too.  I have a few friends who could be considered celebrities, for example, and, now that I’m running WhatsApp again, their details are on the Meta servers…

Except, of course, that they aren’t… at least, not really because of me.  

I was taking a stand to alert people to what Meta were doing, but it’s clear that most of my friends didn’t really care that much.  Many who actively didn’t like Facebook didn’t realise that WhatsApp and Instagram were the same company.   But lots of them had Gmail accounts, or used Android phones, anyway, so security & privacy weren’t too high up their list of priorities.  And it turns out, of course, that most of them are already on WhatsApp and Facebook and Instagram themselves, so not only were their details already known to the servers, but so were mine, because of them.   My virtuous stance was a bit of an empty gesture. (Besides, I hadn’t been quite as pure in my dedication to the cause as I suggest, because I did still have a rarely-used Instagram account, so all bets were really off anyway.)

And so I am now accessible on WhatsApp again, which will make certain social interactions easier.  I still think Signal to be superior in almost every way, and will continue to use it and other services where possible in preference.  But in the end, it came down to my second quotation of the day: the famous observation made by Scott McNealy, the CEO of Sun Microsystems, nearly quarter of a century ago, long before Facebook and its siblings even existed:

“You have zero privacy anyway. Get over it.”

Perhaps he was right. 🙂

Warning Signal

I wrote a couple of years ago about why I really like the Signal app for chat-style communications.  

(Quick summary: it’s just like WhatsApp but doesn’t require you to sell your soul and all of your contacts’ private information to the devil!)  

I’ve been using it for a few years now, for business and social discussions, and it’s been great.  It has very nice software both for mobile and desktop devices, and I know that several people have started using it because of my recommendations, too.

So I thought it only fair also to highlight here one of its key ‘limitations’; in fact, probably its only downside, as far as I’m concerned.  But it’s something fairly important that you may never discover… until it takes you by surprise.

Messages in a Signal conversation are transmitted using end-to-end encryption between the devices taking part in the conversation, and stored in encrypted form only on those devices as well.  Unlike some other communication networks, they are not archived on any organisation’s central servers and, on iOS at least, the messages are not included in any backups of the device.

If you buy a new phone, there’s a process you can go through to move your history directly from your old device to the new one, but here’s the rub:

Both devices need to be available and operational for you to do that.

There isn’t any other method. If you have lost your old iPhone, or it has completely died, then, while you can connect to Signal on your new phone and carry on your conversations, you won’t be able to see any past messages.  If you have them on another device such as an iPad or desktop machine, you should still be able to see your history there, but not transfer it.

There are good security reasons for most of this, and it certainly doesn’t stop me using Signal any more than it stops me using phone calls, but the price of the security is that you should consider Signal messages to be somewhat ephemeral.  Don’t think of them as an archive you will necessarily be able to go back and search indefinitely.  For that, it’s still better to use standards-compliant email… or to copy the important stuff into your personal Knowledge Management System.  You do have one of those, right?  

If so, make sure it’s something that you will always be able to get your data out of in future, like Obsidian.
