Some simple tricks for Mac users. Do you know all of these?

Mustelidae
I’ve just started playing with one of those ‘trail cams’ or ‘camera traps’. You attach it to a tree or similar and it captures movement using an infrared camera sensor, and illuminates the scene with a number of IR LEDs on the front. These cameras are not particularly expensive, and I think it’ll be quite fun.
My first attempt in the wood next to our driveway didn’t quite have my subject facing in the direction I’d hoped! I also spotted several rabbits and a muntjac, but mostly I got clues as to where I should put the camera next to capture more of the nocturnal social life. Coming soon, I hope…
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:
Looking down from on high
Yesterday evening, I got a toy that many of my friends and family were surprised that a gadget enthusiast like me hadn’t been seduced by many years ago!
And today, I took it for a walk. I’m very pleased to discover that Tilly doesn’t seem at all fazed by the drone, only by the fact that I’m not paying enough attention to her.
It’s a tribute to how good the technology is, that a complete amateur like me can produce a pretty video on the first day. Having the sunshine and a light dusting of snow helped a lot too, though!
Take Control of your Video Calls!
Do you wish you could incorporate videos, music, or views from multiple simultaneous cameras in your video calls & webinars?
In this video I take a look at one way in which Mac users can blend multiple media sources, sound and video, and send them out through calls on Zoom, Teams, Webex and similar apps.
A Wee Campervan Caper – Travels with Tilly
Christmas breakfast on the edge of the Cairngorms, 2019
Hello Everybody, and Happy New Year! I’ve been doing something very foolish in 2020, and now I’ve stopped.
Let me explain…
This time last year, over the Christmas and New Year period, Rose was visiting her family in the States, so after dropping her at Heathrow, I turned our little campervan around, and headed north, accompanied by my cocker spaniel. The only thing I knew at the time was that we were spending the first night in the Lakes, and that we were probably heading for Scotland. The rest would be decided en route, mostly based on the weather forecast. I’m not sure if the Dark Sky app is often used as a route planner…
Anyway, I recorded quite a large chunk of our journey with my GoPro, and came back with a ridiculous amount of video footage, some of which had technical issues to overcome, and I discovered I had a mammoth editing task on my hands. I feared it could be well into the spring before I was able to share any of it. And then we had a spring unlike any other. So then I hoped that lockdown would give me more time to work on projects like this, but actually 2020 has been really quite a busy year for me, and it was only once we got back towards Christmas again that I was actually able to devote any time to it.
“At least”, I said to myself, “I have to finish it before the end of the year.” And I did! I clicked ‘upload’ on the final episodes just before midnight last night. 🙂
Now, let’s be clear here: You’ll note I say ‘episodes’ above. There are, in fact, nine of them, and that’s after I’d edited out enough material for at least four more! This is perhaps the most extreme let-me-bore-you-with-my-holiday-snaps variant one can come up with, and I don’t expect the average Status-Q reader to be interested in watching one, let alone nine of these little narratives.
An AirBnB for New Year’s Eve, December 2019

Amazingly, though, there are people who will enjoy my holiday snaps! Some are watching already.
Those longing for the open road amidst Covid restrictions, or those planning their next motorhome trip in more normal times, do like to get ideas for their next adventure, or relive the memories of journeys past, and road trip videos are very popular on YouTube. I’ve watched a lot of them, and some were partly responsible for me buying the van in the first place.
That’s before you get into the experiences, hints and tips of the full-time motorhomers: try searching YouTube for ‘van life’ if you want to enter another world.
But, even though producing this has, in some ways, been a burden that I wanted to get off my shoulders for a whole year, it’s also been a joy. Rewatching my holiday several times over means that some of the best bits are burned into my memory; there are sites, sounds and places that I would otherwise have forgotten in a month, and that I’ll now remember for ever.
And, in the unlikely event that you want to experience any of it too, there’s a YouTube playlist, and the journey begins here:
Sledging through the 5th
This is, I think, wonderful.
When I first saw it, someone had appended a Spanish title, so I presumed that it was created by an artist with whom I didn’t share a language. No textual language, anyway, because this is a testament to how art can capture emotions that we all share!
It was created by Doodle Chaos.
Connecting external microphones to your Mac
If you have a USB microphone, it’s easy to plug it into your computer. But if you have an analog one, intended to be used with anything other than a computer — say, a camera, sound system or voice recorder — the chances are that it may not work, unless your computer has a dedicated microphone socket.
My Macs have a headset socket, into which you can plug combined earbud/microphone combinations such as you might get with your phone. But it tends to think that anything else you plug in there is just a pair of headphones, and that you probably want to keep using the built-in mic on the machine.
I did some experiments to work out how to persuade it to use an external microphone. It’s not one of my slickest videos, but it should serve its purpose!
Update, a few days later:
Even though the above solution works, it’s almost certainly easier, if you don’t have a microphone socket on your computer, to use a USB audio adapter, like this one.
I was hesitant about this, because I wasn’t sure of the likely quality of the analog-to-digital converters in a cheap USB peripheral, but it turns out to work very well for normal use. That would be my recommendation now, if you have a spare USB socket!
Equipment for recording lectures
One of the big challenges facing lecturers in the University here is that, for at least the next term and probably the whole academic year, all of the lectures need to be recorded. Most of the small-group teaching, practical sessions, and so forth will be going ahead — with extensive Covid-prevention measures in place — but there’s no way we can pack big lecture halls full of people in the way we’ve become accustomed to over the last few centuries, so lectures will all be delivered online this year.
One aspect of my University job recently has been to find and evaluate some of the kit people might want to use for recording, either at home, or in the meeting rooms in the department that we’re equipping for this purpose. (At home, the sitting room has been converted into a recording studio for the 21 lectures Rose needs to get on disk!)
I’ve been making videos of some of my tests and experiments, mostly for internal use, but some of them might be helpful to others. If you should be considering purchasing a USB desk-standing microphone, for example, you might be interested in one of my recordings from yesterday:
I’ve been gathering some of these into a YouTube playlist as well:
