Roland D-50 Key Servicing

I serviced my old Roland D-50 today after noticing problems with the aftertouch of two keys. It seems the key contacts need yearly mending to work--I took the whole thing apart about a year ago, cleaning all 61 keys and their contacts.

Here's a useful web page for those of you who have a D-50 in need of servicing.

Flight Sims

There is a terrific open source flight simulator called FlighGear. It's freely available for my platform of choice, Debian Linux (and a number of others, including Windows and Mac OS X) and it's quite mature these days, so naturally it's what I run when I want to fly a plane these days. When I still had a Windows partition that worked, I have to admit I quite liked Microsoft's classic Flight Simulator, but my Vista partition doesn't work all that well and anyway, Microsoft killed off the sim a year or two ago. FlightGear is a more than adequate replacement.

Today I learned that somebody is marketing an older FlightGear version under a different name (Pro Flight Simulator), charging around $50 for a DVD or download and promising free lifetime updates. Of course, there is no (easily found) mention of FlightGear anywhere on their site, and I doubt the source code is easily available, either.

It has to be somewhere, though. See, FlightGear is GPL software, which basically means that you can do whatever you want with the software (including selling copies of it) for as long as you also make available the source code. I think GPL lists a few other conditions as well, but the idea is that software should be free (as in speech).

So what these people do when ripping off free software is most likely not illegal, merely unethical. To further firmly establish themselves in the gutter, they have produced a number of blogs and fake reviews to market the product, seemingly without any shame; do a Google search if you are interested, but I won't help their cause by giving you a direct link.

Read all about the scam at http://www.flightgear.org/flightprosim.html, and download a FREE copy of the latest version if you are interested in flight sims. Or just spread the word.

Me and XML in Stockholm

I'll be talking about XML in Stockholm on June 16th. The event is a one-day tutorial for technical writers, managers and other interested parties, organised by Dokumentinfo. They organise tutorials on various subjects related to document management and archiving, and a yearly conference where I was invited to speak last year.

So far I have few details but I'm pretty sure I'll manage to include XLink, somehow.

Finally, KDE 4.6 on Debian

Again, title says it all. I'm only a few days into running KDE 4.6 on my desktop but so far it's superior to any previous 4.x. It feels like, well, it just works. It's also beautiful; Plasma is finally mature enough to do all those things I read about two years ago.

What doesn't work all that well is Amarok. It still won't play CDs (it can now list the CD contents - hooray), and while I do understand that some of these things take time, 1.4 didn't have any problems in that respect. I still haven't found an alternative for my every music need but out of spite I'm now running Clementine, an Amarok fork that also doesn't grasp CDs.
