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.

I know I’m (very) late to the party, but nevertheless, here it is:

Welcome in my computer stable, Raspberry Pi!

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!

Here in Europe, thanks to the surge in homeworking, there is no way to get your hands on a new webcam – they’re sold out everywhere. So I tried another solution for my older desktop machine running Xubuntu.

While installing Droidcam on Xubuntu, I encountered the following message:

gcc: error: make: No such file or directory

Strange, since I had just installed the complete GCC.

But while the GCC may have been complete, ‘make’ is a separate tool. The simplest way to install it is:

sudo apt-get install build-essential

It’s easy, once you know – but I can imagine that it’s not that easy if you’re not a developer (or a seasoned Linux user). But neither is getting Droidcam to work on Ubuntu, by the way – it takes a lot of tinkering to get it to work over USB, including the right developer mode settings on the phone as well as installing the ADB tools on Xubuntu with:

apt-get install android-tools-adb android-tools-fastboot

Now I just need a longer USB-C cable to position the phone above my desk rather than below it!

Can’t use this camera position in Skype – where’s that long cable?

As an aside: the lsusb on Xubuntu recognizes my Samsung Note 10+ as a “Samsung Electronics Co., Ltd GT-I9300 Phone [Galaxy S III] (PTP mode)“. I never connected my S3 to this copy of Xubuntu, so there must be another explanation for that weirdness…

I have written about my tribulations with the Xerox Phaser 3260 laser printer earlier this year. All in all, I’m happy with the machine: it’s probably not the cheapest option but it worked without fail for many years now, mainly helping my children with their homework and their university courses.

The trouble I wrote about earlier was in fact solely due to the appearance of Mac OS “Catalina”: this version of Mac OS requires 64-bit drivers, which were unavailable from Xerox for a very long time. During the whole process of trying out how best to work with different versions of Mac OS and the corresponding drivers I also turned on AirPrint in the printer settings. I did not hope to solve our problems that way, but in house full of iPhones and iPads AirPrint comes in handy. And turning it on for the Xerox is just a matter of clicking once:

As it turns out, this is actually the easiest way to get any Mac to print to the Phaser – even without any printer driver software. So here’s my tip of the day: if you are the owner of one or more Mac’s or iOS devices, make sure your printer understands AirPrint and turn it on! As long as you don’t need any fancy features of your printer, say for printing photos, this is the easiest and quickest way to get your printer working for you.

If I ever need to buy another printer, I’ll make sure it understands AirPrint ;-)

Last year, my brother moved to a house in what we would (almost) call the countryside. The lockdown provided him with lots of time to clean up his garden, which includes a chicken coop and a greenhouse – we all hope to be invited for a celebratory BBQ, by the way ;-)

Guess what he found in the chicken coop: a mouldy camera bag with a camera and a few lenses. Photography being one of my interests, he dropped the bag at my door last weekend. I investigated the contents: the bag went straight into the rubbish bin.

The camera turns out to be a Mamiya/Sekor 500 TL, a single-lens reflex camera for M42 lenses. It came with an uninspiring Auto Mamiya/Sekor 1:2.8 50mm lens.

The Mamiya/Sekor 500 TL

I found a few references to this model on the Internet, and having handled one myself I can understand why one (recent) review calls this camera “big, chunky and disappointing“. It is indeed well-built and probably very strong camera, but it’s also quite heavy.

The Sekor 500 TL was introduced to the market in 1966, but I guess the one I have here is younger than that. Contrary to the 1966 model, it does have a self-timer. As a nice addition, it also includes a detachable (cold) flash shoe accessory from Asahi-Pentax; I guess those two brands had similar prisms on their cameras, or it would not have fitted so well.

The Asahi Pentax flash shoe

I already have a few camera’s in my collection, and this could be a new addition… but this particular item is damaged: it has a serious dent. I’m not even sure the back closes correctly, which is essential for any camera.

The dent is quite serious, given the heavy construction of this camera

Even if there is no internal damage such a dent makes the camera probably worthless. My shelve space is rather limited, and that makes me wonder: should I really keep this one, dent and all?

PS. These are my first “product stills”, and I know that I have a lot of work to do on the white balance of those pictures!

Meteorologically speaking April was a warm and sunny month in Belgium, and that was clear from what we saw in our garden: the grass grew very fast, and our trees bloomed two to three weeks earlier than normal. Local tradition demands that we wear Lily of the valley (Convallaria majalis) on the International Worker’s Day events. It has been quite a while since the lily of the valley plants in our garden bore flowers on May 1st; this year, they were almost all gone before that day!

The first open flowers on our lily-of-the-valley already appeared on April 10th.

Those warm and sunny conditions are of course reflected in our solar energy production numbers. April numbers ended at almost 115% of the average for the month, and only two Aprils did better – almost a decade ago, when the reflective coating on the roof was still really reflective ;-)

I may not have much faith in Samsung’s will to do what I think they should do: keep the software of their devices up to date for more than 2 years. But I must report that the Galaxy S7 received another update to its OS: at least the Android security patch level has been upgraded to the version of March 1, 2020. Keep it up, Samsung!

Minor updates only – but that’s better than nothing!

Yesterday, I have been informed that one of my best friends has been found dead in his appartement. I have known him almost all my life, and we have done many things together: we went to school together, sitting in the same class for twelve years; we went together on holidays and trips, first with our parents, and later with friends or just the two of us; we talked about books and people and movies and literature and art and … life. He was smart, he had a phenomenal memory, he was able to see through fake reasoning and irrelevant propositions in a debate, he fiercely defended a rational and scientific approach to anything, and he always strived to make the world a better place for all people.

Making the world a better place was very important to him. How ironic then, that the Corona pandemic and the measures to fight it played a part in his dead. No, he was not infected. But he was a “loner”, in more than one meaning of the word. He had no partner, no children, no living parents, no siblings, and just a few friends… He was more of an observer of crowds than someone to voluntarily mingle and interact with people. Something from his past – we’ll never know what – weighed heavily on him, rendering him moody and depressed. But he still loved a good talk, and we had many, if not always in person.

Not being able to retreat to his caravan during the weekend and his days off work, in the woods and calm of the countryside, during the last weeks was very hard on him – he told me as much 14 days ago. Not being able to visit his friends for the weekly dinner probably downed his spirits as well.

The so-called “social distancing” we all have to practice to counter the pandemic is without any doubt required if we want to limit the stress the disease can put on our lives and the economy. But it is so badly named: we don’t need “social” distancing, we need “physical distancing”! Man is a social animal, and in times like these meaningful social contacts are essential to fight the limitations that the war on the virus induces in our mind and spirit. If we can’t hug our family and friends in person, then at least we have to call them, write letters and emails, interact with them to let them know we care, to tell them that soon things will be better. Not just once, but often. Because if we fail to do that, I fear my friend won’t be the last one to die alone, while feeling abandoned and desperate…

I was a fan when the series was aired here in Belgium, and I’m happy to see that M*A*S*H still is relevant today!

What a lovely combination! Just the right thing to saunter through a sunny spring landscape… if only there was no pandemic about.
