I discovered Scott Helme’s blog only recently, but I’m glad I did. Scott knows much more about HTTPS and certificates than I do, and he succeeds in explaining the subject in a very understandable way. The post that pointed me to his blog explains how certificate “Revocation is broken“. And that subject has some surprising aspects, by the way. Earlier posts on his blog will let you discover what SSL means, how you can install certificates, what to look out for, and more.

Let’s face it: I’m happy to blog here on the WordPress site, which takes care of all the SSL stuff for this blog (and probably does it better than I could do myself at this moment). But if I want to continue to help build and run other websites, I’ll have to get my hands dirty on this subject! We may all be waiting for the days when “buying” a domain name will include the corresponding SSL certificates, but as long as that isn’t the case, you and I will have to do it ourselves. That’s where people like Scott can be a big help.

I have updated the numbers on our electricity production. There’s nothing exceptional to report. If anything, a number just below average isn’t surprising, considering the many half-cloudy days of July. It seems contrary to to expectations, but the heat of many of those July days did not come from the sun, but from hot air blown coming from the South.

We had at most two days without clouds; if there are numbers on that somewhere, then surely July 2017 will be very much below average on that count!

The title of the article on this German motorcycle website is not exactly correct, but it may well point to something that will soon be a reality: “Südtirol sperrt ersten Dolomitenpass. Experiment am Sellajoch“. No, this alpine pass, the Sella Pass, isn’t permanently forbidden for all traffic. But local authorities are experimenting with an interdiction for all cars and motorcycles powered by combustion engines: this summer, only cyclists and electric vehicles – and horses – can travel over the pass on Wednesdays. I can appreciate the words of Reinhold Messner, one of the supporters of this measure, as quoted in the article:

Damit die Berge wie vor 200 Jahren genossen werden können: Der Berg ist ein Ort der Langsamkeit und des Schweigen, nicht der Geschwindigkeit.

Translated to English: “That way, the mountains can be enjoyed like 200 years ago: the mountains are the realm of slowness and silence, not a place for speed“.

Some cities have already set the first steps into a future with more electric vehicles, and now the mountains could well be next in line. I understand the rationale behind that strategy, even if it means that I can no longer wait too many years to try a few mountain passes myself (or invest in an electric motorcycle, of course).

The weather was very dry last month in Belgium, and our farmers don’t like that. In terms of sunshine, the month was rather average. Our solar panels registered 102% of the average solar energy production for June over the previous 7 years: better than expected after the low numbers so far this year, but far from exceptional.

On to July and the summer holidays!

The weather of last few weeks of May Was relatively sunny, here in Belgium. Nevertheless, the solar energy production of the past month ended up (slightly) below average, and below the target of 290 KWh that I hoped to achieve.

What our cells need, is lots of sun and temperatures that don’t go into the high twenties or more (Celcius!) – but that combination is rather rare here in summer.

Less Sun In April

Quick update on our solar energy production: April 2017 produced a “below average” number of KWh. The total is similar to last year, but almost 15% below the average of the past 7 years. That’s three months in a row dragging down our averages – let’s hope the rest of the year does not go the same way.

As Engadget writes:

It’s a tragic time for both music and technology. Ikutaro Kakehashi, best known as the founder of Roland Corporation, has died at 87. The engineer turned corporate leader got his start making electronic drums and rhythm pattern generators, but it was after he founded Roland in 1972 that he hit the big time. His company quickly became synonymous with electronic music effects, and the machines built under his watch didn’t just become popular — they changed the cultural landscape.

It’s safe to say that digital sound as we know it today would not have been the same without Kakehashi.
