[Flightgear-devel] OpenCL
Hi, I'm still in the middle of a project but I am having quite some interesting stuff here. There is a strong-crypto subproject which uses FPGAs with OpenCL. I have learned that also the ATI and NVIDIA GPU drivers support OpenCL in addition to their proprietary stuff (CUDA, etc.). During a presentation, the tech-guy said that e.g even modern game engines also use CUDA or OpenCL for the physics engine and those hypothetically could also run on the FPGAs then. I was wondering if anybody has ever given thought to this stuff. Considering that a reasonably good GPU has about 20x the computing power of a quadcore CPU, using OpenCL as some kind of abstraction layer (there's also OpenCL implementations for CPUs, of course) would be a hell of a cool thing. Power users or people who want to build simulators for real training could just buy another GPU or an FPGA board to get an extreme performance boost.

So i suggest to remove all urls that do link to such individual scenery projects from the FlightGear website, the wiki and even postings on the flightgear forum. Especially the latter might be very important. With this you will reach 2 things: 1) A HUGE discussion and flamewar about censorship and freedom of speech in the forum which will eventually do a huge damage to the project and it's reputation. 2) Legions of heavily pissed users which then simply use Google to find their addon-scenery. 3) Likely new websites and forums coming up for Flightgear, causing a spread and segmentation of the userbase. What you will NOT achieve is that individual scenery designers stop working on their individual sceneries and start working on the global scenery. As Thorsten Renk made very clear to me in the forums, Flightgear works so that everybody works on what they are interested in. Not more and not less. I think, the licensing issue is maybe a bigger point than it's being given credit for. It seems to be very hard to create really pretty scenery which is GPL compatible. I'm not uptodate, but I remember something about e.g. CORINE being not GPL-compatible. The FG scenery-database, however, requires contributions to be GPL-compatible. Now we are back to what people are interested in... If I think about myself personally, if I would go through the hassle of compiling and learning to handle this monster Terragear, I would do it to create the best possible VFR scenery for Western Finland. That would be my interest. For Finland that would very likely include using non-GPL-compatible sources, because e.g. I haven't found any GPL-compatible good resolution elevation grid yet. However, I could obtain permission to use the elevation grid from the national survey service for the project, which would allow for free redistribution but it wouldn't be GPL-compatible. So whatever I would create, couldn't go to the scenery database. It is one thing if you yourself work by a certain system but trying to force people into your system is not only plain wrong - it will inevitably lead to people either leaving the central areas (i.e. forum) or even leaving the project as it is. You cannot publish free software and then try to blackmail people into doing stuff the way you want it. That's stupid and ridiculous.

From my experience building scenery I would say ... building Western Finland in a good matter will take approximate six months when you’re fast (while making the monster small will take two or three days). I'm not waiting, I'm on my way :). The issue for me is less the compiling part but the handling part with everything included. I have never had any contact with GIS stuff and all the concepts and terminology is very foreign to me. It will take a while until I dug through all the specific lingo and how to use the tools. Then I have some practical issues to figure out, e.g. that the GIS software I tried runs extremely slow on my machine. It takes literally minutes to build the screen after every move, zoom, etc. Where have you been looking for? I can provide you some GPL compliant data when it is necessary. Just send me a note or ask at the forum. Actually, I have asked another user who offered the data a short while ago and such has Alral publicly in the EFTP thread. Trouble is, SRTM seems not to go beyond 61°N, so I was googling a couple of hours for elevation data Finland and found only one source which I am not clear about the licensing. You cannot publish free software and then try to blackmail people into doing stuff the way you want it. That's stupid and ridiculous. I think no one is going to blackmail anyone recently. I’ve never seen censorship here before and I don’t like such approaches at all. But of course, like the GPL discussion shows, this project follows some rules. In my personal view it is not stupid and ridiculous to HELP new developers to follow this rules. This was specifically an answer to Kreuzritter's suggestion to remove all links to custom scenery from all official FG websites to force people to create scenery for the central database. I would consider this kinda blackmailing or trying to force people into something. Of course, the project follows some rules and I don't have any problems with the fact that the scenery database is GPL'd and thus contributions must be GPL'd too. I would only have a problem with any attempt to subdue custom scenery, because IMHO, for the user it doesn't matter if the scenery is GPL'd, PD or any other license that allows for (cost-)free distribution and use. For the user it only matters to have pretty scenery.

The charts are republished this way, and charts could not be transformed to a GPL source by a personal-referencing-and-copyright-project by Syd. I am referencing the copyright and restriction of NAV CANADA (in case!), and his statement about using (unknown) wms sources for scenery projects ... This seems to be pretty tough lawyer stuff, so I think, unless one here is a lawyer with focus on copyright law, we won't get a solution, no matter how much we discuss. I would like to suggest that somebody from the FG core (scenery) team contacts the Free Software Foundation. They have specialized lawyers and they do exactly this (among other stuff) - provide legal advice to Open Source projects. My suggestion would be, that somebody from the core (scenery) project requests advice from the FSF and following that, a precise guide or code of conduct for scenery developer will be written. That should remove anything that's unclear and give a good deal of safety and security for (would-be) scenery designers as well as for the project itself. E.g. I'm using official airport charts of the Finnish Aviation Authority (public domain) and aerial images of the National Land Survey Authority as referencing material for my EFTP project and to my understanding and according to information I received from the National Land Survey by phone, only the redistribution of the material itself would be a problem but not of anything I produce while only using the material as a reference. However, as written elsewhere, this might very well differ from country to country. If you think practically, this also makes some kind of sense, because I doubt heavily that the current apt.dat was created by volunteers, walking through every airport and measuring all data themselves. I am fairly certain, that in the creation of the current apt.dat, some official material was used as reference.

[Flightgear-devel] SPAM in the MP world
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi, I was just flying around EFHK without suspecting anything. More or less quickly, some MP user with the CS dromade appeared in an ufo, circled around me, asked a few questions like do you like great airports, then sent an URL from the .br space, said hugs from Amsterdam and vanished. I think, we should seriously do something about this kind of stuff before the MP world becomes a popular place for spammers, like e.g. have the MP servers filter URLs out from the MP chat...

[Flightgear-devel] Bug in config file handling
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi, sorry I didn't open a bug in the tracker for that. Normally I do but in this case, I'm not sure how to do write it. When trying to get Thorsten's Sunrises 1.1 to run under FG2.6, I found out that there might be a problem with including files via --config. I use my own ~/.fgfs/mypreferences.xml to set some properties like multitasking, my modifications to the fligh recorder and such because I use the OSBS repo with autoupdate which always breaks my changes in preferences.xml. During my tinkering with Sunrises 1.1, I added the following for the sim/ section: systems property-rule nameLocal Weather Rules /name pathEnvironment/local-weather-rules.xml/path /property-rule /systems This did activate the local weather rules but afterwards, there was no METAR being parsed any more. After testing, I found out that the property rules from preferences.xml property-rule nameEnvironment METAR Interpolation Rule/name pathEnvironment/metarinterpolator.xml/path /property-rule property-rule nameEnvironment Interpolation Rule/name pathEnvironment/interpolator.xml/path /property-rule were not in the property tree. After some more testing, I feel confident to say that putting the local weather rule to mypreferences.xml broke the property rules from preferences.xml. As far as I understand, files included with --config are to be merged in the property tree, hence I would classify the described behavior as a bug.

[Flightgear-devel] EFTP airport development
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi, as I already announced in the forum, I'm currently working on improving Tampere-Pirkkala Airport (EFTP). I have already created a verdetailled v850 airport file from the official aerodrome charts and from aerial imagery with WED, containing the runway, civilian and military apron and civilian and military taxiways (the stock version only contains the civilian part of EFTP) and a simple groundnet with the parking positions. Today I have set up a gitorious repo for the development at https://www.gitorious.org/eftp4fg Now, would somebody with a working Terragear installation be so nice and generate a tile (can be in water) with the airport, so I can verify the v850 file and start placing objects and buildings?
