I have updated our solar electricity production numbers with the lowest yield for any September for our installation. 2017 will probably turn out to be a “bad” year for our panels.


Go, Catalunya !

It’s been a long time since I suggested that a system like S5 should include an editing mode, and see my post of March 15, 2012 repeated that suggestion. As it turns out, there is now a very similar tool that does just that: remark. No, it’s not a Wiki, it’s a lightweight CMS, using Markdown (plus extensions) to do its magic.

To be honest, between my first suggestions in 2005 and now a number of similar tools have been created, many based on S5, by the way – just check out http://wiki.s5project.org/HTML_slideshow_tools. But things over there aren’t too lively anymore, it seems…

I’m waiting for a good opportunity to try ‘remark’ out, if only to see  on how many platforms it can be used for editing without too many limitations.

For a quick try-out, head over to Platon.io – it’s an editable webpage powered by remark.

Normally I wouldn’t blog about cars – I prefer motorcycles or even bikes. But this one is special. Very special. I owned one when I was a kid, although mine was just a Dinky Toy, of course. But it was the most beautiful car I knew then, even beating the Batcar in coolness.

And now Jaguar has converted a 50-year original E-type into an electric car, that drives like the original, just a bit faster! Too bad I don’t have the money to buy one. But I would love to drive one for a day, somewhere in the countryside on a good summer day…

Thanks, Ars Technica, for telling me about this car!

Just so I don’t forget it myself: I’m using Grive2 to backup a few hundred files to Google Drive from the little Asus portable. Why? Because I finally took the time to automate the daily readout of our solar panels on that little Linux machine, and I don’t want to lose that information (one little file every day!) should anything happen to the portable.

I found the instructions on how to install and use Grive2 here: “How to sync your Google Cloud on Linux with Grive2“. Basic stuff, easy to execute: ideal for an eternal beginner like myself ;-)

I had to change the crontab entry, because the line in the example wasn’t working for me. I replaced the ‘grive -path /home/wouter/somedirectory‘ part of the crontab entry with ‘cd /home/wouter/somedirectory && grive‘. And that did the trick.

There are other solutions, of course, but this was sufficient for me, at least for now.

PS. Yes, I really should replace that machine with a Raspberry Pi… but that will have to wait until later.

I’m currently trying to automate the creation of datasources in ColdFusion server instances, in order to facilitate a number of migrations our machines and applications have to go through. For the record: this turns out to be reasonably simple, once you get the knack of using the ColdFusion Administrator API classes (if I find the time, I’ll write about that later).

One thing slowed me down: a typical error message without much meaning. This is what I received when recreating (or at least trying to recreate) an Oracle RAC datasource:

java.sql.sqlrecoverableexception: IO Error: NL Exception was generated

I wonder why developers often invent error messages that do not tell us what really went wrong. In this case, it turned out that I forgot to copy a single closing parenthesis at the end of the JDBC connection string. Let’s call that a syntax error, Oracle, and please give a significant message if I mess up! Or is it Adobe’s ColdFusion that is hiding more explicit and clear details about what went wrong?

While we were on holiday in Slovenia, we saw several dozen (if not hundreds) of Harley-Davidson motorcycles on the road and on parkings. Clearly there was some kind of reunion going on during the first week of September. And right in between all those Harleys we found a BMW R1100S on the bank of lake Bled. To top it off, the bike did not look like the almost 50.000 km on the counter: it was spotless and perfectly maintained. I enjoy my F800GT a lot, but the R1100S has stolen my heart – and bikes like this are the reason for that. Congrats to its German owner.

PS. I couldn’t get a better image of this bike all by itself, since there were too many other bikes around it. A shame, because it was worth a more glorious picture!
