Nokia N9 and CalDAV on Google

-
Wow! It's some 18 months since I last published anything here! Time to add a quick article that puts in one place the results of something I was looking at last night.

The idea here is to synchronise your Google calendar(s) with your N9 (and presumably N950 since they both run MeeGo Harmattan), which isn't that hard in itself. What caught me out and had me searching was how to sync all my Google calendars with the phone.

Single calendar

In its most basic form, this system allows you to sync just your main Google calendar with a mobile device.

On your phone, go into "Accounts" and start setting up a new CalDAV account:
Fill in your Google e-mail address (eg. your.name@googlemail.com) and your Google account password, and in the "Server/URL" field enter: 
https://www.google.com/calendar/dav/
Tap on the "Sign in" button and you will be presented with a page allowing you to set up the scheduling (just like with any synchronised account) and showing you the calendar that's going to be synced and added to your phone's calendar:
What frustrated me was the fact that I actually have 2 calendars on my Google account and only one was showing up. I wanted both. Clearly, Google wasn't exporting both calendars.

Multiple calendars

Point your browser (mobile or desktop, it doesn't matter) at this URL: 
https://www.google.com/calendar/iphoneselect
You will see a list of the calendars you have and you will be able to select which ones are to be made accessible to CalDAV clients. Select those that you want to export and click on the "Save" button. Now go back to the CalDAV account on your phone, tap the "Sync" button, and all the accounts should appear and be added to the phone's calendar:
Furthermore, any changes made to events in those calendars and any new events added to them should make it to the online version on Google once everything has been synced again.

HP Prime benchmark

Err, right. The HP Prime is hardly a vintage calculator given that it was first released in 2015. Better still, HP released the so-called Prime "G2" in August 2018 with faster hardware, much more RAM to work with and double the storage space in flash memory. When that happened, there was no excuse, I had to get one. At the time of writing, the Prime G2 would appear to be available only in Europe. The Americas have been left by the wayside this time around. I bought mine from derekenwinkel.nl with whom I have no affiliation other than being a happy customer of theirs. As it became known that there was an updated version of the Prime, people in the Museum of HP Calculators Forum were interested in hard data showing the improvements in performance, so I went and wrote a benchmark. The benchmark in itself is probably of limited value in absolute terms but gives a good idea of the differences between different machines. A benchmark run can comprise up to th

Is it really a Hewlett Packard?

There are two scientific calculators recently produced that, I'm afraid, fall into the cheap, plasticky category. They are the HP300s+ and the HP10s+. The question is, are they really Hewlett Packard machines at all? They are not. They are in fact Casios that have been rebadged to look like HP machines. Want proof? Watch this video with the HP10s+ showing its real colours. If you press the MODE key four times you get to the menu where you can alter display settings. There is an undocumented function in this menu where, if you press '2', you get to the contrast setting. This is not mentioned in the manual and, indeed, it has no effect, but look at what you get on screen when you press '2'. One good thing about this little machine is that I didn't even have to put a battery in it. The solar panel above the screen provides enough power to run the calculator as long as there's enough light around.

Egg timer in a 41CX

Now this is something unusual. Who would want to use a 30-year-old machine worth something as a mere egg timer, or use it at all in a kitchen, where it could easily get damaged? It just so happens that one of the machines in my collection is a SwissMicros DM41. It's built really solid and it's basically the same thing as a Hewlett Packard HP-41CX in a case the size of a credit card, so that means that it incorporates, among other things, a Time Module, which gives it a stopwatch, countdown timer and alarm capabilities. The DM41 is a great little piece of technology. However, the operative word here is "little". While its LCD is the same size as it's Voyager-sized big brother, the DM41L, its keys are just a bit too small for the device to be fully practical, but for some things its form factor makes it just right. Okay, it's more than an egg timer. This said, my DM41 gets used most of the time in the kitchen as a timer while I'm cooking. I keep i
