In 2017, I was looking for a wrist-based device that would do three things:

  • keep an eye on my heart rate at all times;
  • serve as a subtle alarm clock;
  • last longer than 24 hours on a single battery charge.

I was lucky to find a refurbished Huawei Fit with standard warranty for little money, and I must admit that it did exactly what I wanted. The heart rate numbers registered by the device were pretty close to those that appeared on the cardiologists monitor. I only overslept when I really wanted to, ignoring the gentle buzz of the Fit. Just having a black and white screen was good enough for me, and that screen clearly helped to realise my third requirement: it would easily last for 5 to 6 days on a single charge without being too big and bulky. The Huawei Health app was (is) not ideal but certainly sufficient for my purposes.

Since a few months however, the Fit slowly started to degrade. Not by failing, no, but the battery performance started to get worse. And energetic physical exercise, like working in the garden, resulted in water vapour (sweat!) on the inside of the glass, rendering the screen unreadable for many hours. Time to look out for a replacement.

I surveyed the large field of activity trackers, sport watches and smart watches (if only because it is hard to distinguish those categories and the devices in them). I have no need to add applications to my watch, but I do want a measure of interaction between the watch and my phone – hence a certain measure of “smarts” is required in the watch.

Finding a replacement turned out to hard: the number of available smartwatches and activity trackers has grown, as have their features. But when you look at the battery life, the manufacturers seem to have problems extending the battery life of those new devices substantially. The Apple Watch hardly lasts a day. Android Wear devices can get you through two days if you’re lucky. Garmin has a few devices that do (much) better – if you are an athlete, you can do worse than pick one of their watches.

In the end, it turned out that the real champion of battery life is still Huawei, with the GT 2 series devices. By the way: the Honor MagicWatch 2 is almost identical to them. I saw the Huawei GT 2 on the wrist of a colleague, who spoke very favourably of it. My wrist is rather thin, so I chose the GT 2e for a better fit. 46mm is large, but I wanted to maximise the battery capacity.

I had to wait a few weeks to get it delivered (so much for webshops that promise stock availability and overnight delivery!) but I will say that so far I am quite happy with it.

The Huawei GT 2e is a large device, but it just fits my wrist and is quite comfortable. The sporty strap is a lot better and less sweaty than the one on the Fit. There is currently no real choice in alternative straps, and that is one thing I look forward to: for a more formal occasion I would like to be able to change the strap, but it would have to be a strap that closely fits to the watch’s body, like the original.

Old and new on the same arm ;-)

The screen is very nice, although not as bright as I expected: in bright sunlight some effort is needed to read all details. Functionally, it does more than what I want or need, so I have no complaints there. Did I mention that it is a relatively cheap device, compared to similar sport watches? I hope this one will last at least 3 years as well, and possibly more.

I do have a wish, though: Huawei should work on the iOS version of its Health app. Compared to the Android version, the iPhone version is missing more than a few things that I would like to use. Being able to tune the app notifications in more detail is my most important request. So there you have it, Huawei: the watch is good enough, but it will take an extra effort on the iOS app to make it even better!

Professor Ed Hawkins (University of Reading) has constructed a visual representation of the of the change in temperature as measured in each country over the past 100+ years: blue means “colder than average”, red means “warmer than average”. Check it out yourself at https://showyourstripes.info/.

Since a large part of the Earth’s surface is covered in water, it is also interesting to have a look at the graphs for the oceans. There are striking differences in the temperature evolution of the North and South Atlantic Ocean respectively. Even more extreme is the graph for the Arctic waters: look at all that red in the last 15 years!

My setup has been the same since quite a few years now: I have a Keepass file on Dropbox, and I use several different applications and apps on multiple devices to access and update that file. Which applications, you ask?

On my Macs as well as on my Xubuntu machines I will use Keeweb. Despite its name, it gives you a desktop application that natively accesses (and syncs) files on Dropbox. This is the application I go to for when I want or need to reorganise the Keepass file, e.g. to rearrange groups or import lots of account data.

I would use Keeweb on a Windows PC as well – if I had one. At work, we have no free choice of which application to use to store passwords, but luckily we do have the “official” Keepass Password Safe at our disposal.

On Android my favourite Keepass app is called Keepass2Android. I will admit that I made that choice a few years ago, and haven’t checked on its competitors recently (are there competitors of note, by the way?). But it does what I need it to do; it accepts Dropbox as cloud storage and it will even merge changes from the local version and the Dropbox version when it detects differences between the two during the synchronisation process. That last one is a killer feature, and it hasn’t failed me a single time in the years I have been using it.

On iOS the situation is a little more complicated – at least, that how it feels to me. I wrote earlier about KeePassium, and that is still my app of choice. I like the interface, and it does all I need when I look for account info (you can store more than just passwords there!).

But in order to sync my central file on Dropbox, on iOS the app has to go through the “Files” app from Apple. Files-the-app is capable of showing files of all kinds on the iOS device, as well as the files on several cloud file systems, like Dropbox. What is less clear to me, however, is how quickly “Files” notices changes on Dropbox and picks up the latest version of my central KeePass file. I also have had trouble getting the latest version of my file (as changed on Android, for example) onto my iPhone. Although I must admit that the last few weeks fared better: I haven’t noticed anymore missing syncs lately. What I can’t say is whether the issue was/is with Files rather than KeePassium or even my internet connection…

Anyway, when it comes to passwords I want to be sure that I’m not missing any information – or worse: I don’t want to overwrite my updated central file with an older version on iPhone! That’s why I currently always check the “last updated on” date of my Dropbox file in Files before opening the file again. Of course my Dropbox account is protected with a password, but I don’t think that is what Andrei Popleteev means when he’s writing about “How to sync KeePassium with Dropbox“.

Manually checking the file date on iOS is not an ideal situation, I know, but to me that check is a small price to pay for the greater good of having my account data available on all the platforms I use! And for me, KeePassium is still the way to go on iOS.

No, I’m not going to gut my Macintosh SE/30 to use it as an iPad stand.

But yes, this is a cute mod !

Yes, “warm” and “sunny” are again the words needed to describe the local weather during May 2020. The COViD-19 measures keep us close to our house, but when we go for a long walk the atmosphere is that of a summer holiday walk. There is much less traffic on the roads, and you encounter more people walking or riding a bicycle. All that enhances the holiday feeling, and takes away a big part of the pre-Corona pressure to rush and hurry. It may seem contradictory, but yes indeed, during those walks we feel like we’re on holiday – even in the midst of a serious crisis.

May 2020 was sunny, indeed: it failed to set the highest electricity production number for the month of May in our installation by a hair. Only May 2011 did slightly better (332KWh vs. 330Kh), and that was in a time when our panels were still very new!

All that sunshine is fine – except for our garden (and for the farmers). The spring of 2020 is sunny and warm, but also very dry. This is not the post where you might expect this phrase, but here it is nonetheless: we need rain too!
