The mostly excellent Sygic navigation app on WP10 needs attention. I had set it to warn me of approaching railway crossings but it can't differentiate between those and tram routes. And trams ? are a major part of Melbourne traffic. I have deselected that setting.

We have ULP at 91, intermediate at 95, premium ULP at 98 & E85 for Flex-fuel engines, that's 107 octane.
Back in the 90s, in Europe the Ford Mondeo & Opel Vectra were competing for the same market share, both used the European base level fuel of 95 octane and the Mondeo offered better performance.
When they went on sale in Australia, only the Vectra was modified for 91 octane, meaning that, on the standard, base-level fuel, the Vectra outperformed the Mondeo. And there's usually 4c per litre price difference between 91 & 95-octane, unless you use 95-octane E10, which is a few cents per litre cheaper than the 91.

I had to refuel yesterday sometime, so when I stumbled upon a fuel outlet selling 91 RON (base octane) petrol at a 10% discount I filled up there.

Windows Phone 10 is weird in some ways. I had the choice of Edge browser or the old WP 8.1 version of a PDF reader to open a PDF. I chose the reader. A notification on to of the screen suggested Edge was a better choice & had a hyperlink reading "why?"
So I tapped it. The notification then said the PDF reader was no longer supported, yet it had effectively opened the file.

I'd used the wrong process, which I didn't know until my phone call. Wasn't mentioned anywhere on their website that a simple phone call could get it done in minutes.

I had just ended the call to the carrier to port my mobile phone number from the old micro-SIM card to the new nano-SIM card when all cellular connection died.
So I turned on the flip-phone I had put the new card into (with a spacer adaptor) and found the number working on that phone.
I then swapped the SIM cards over. All done, all good.

Made the move to Chrome instead of Safari as the default browser on the MacBook Air because an as-yet unsorted problem with the user account means the Safari icon bounces in the dock for between 7 & 31 seconds before opening.
Safari behaves normally in other user accounts.
I have imported Safari's bookmarks & set up pinned tabs to mirror those on Safari.

TIL that HDR pics taken with the Lumia 1520 have a slider control where lighting levels can be adjusted.

Another case of Sierra's PDF bug: Every 2 months I submit an annotated crossword puzzle for publication in the Mac User Group's monthly magazine. The last two issues, December & March (no January edition) have had the annotation layer stripped out in the process of emailing it to the editor.

So in future I'm going the export the annotated PDF as another PDF (this flattens the annotations layer & fixes it to the rest of the image) and send the editor both a zipped file & a Droplr link of the same. http://d.pr/f/6tLC

Looked at an expensive (> $55) mobile phone cradle to use with the big Lumia 1520. It's a suction cup mount with an adhesive suction surface that can apparently/allegedly cling to rough/uneven surfaces. Next there's a swivelling ball joint & a very powerful magnetic plate of about one square inch in area. The kit comes with two very thin steel sheets that are stuck to the back of the phone (one on the phone & one spare), and can fit between the phone & any case it might be in.

But that was too expensive/complex. The lumia 1520 is 3½ inches wide, the adaptor I chose can open to at least 4 inches. This one was chosen for that reason & that it would fit my current windscreen mount.
