The format is defined at: http://www.json.org/ Basically you are allowed strings, numbers, arrays, and object, which would be called a map, an associative array, a dictionary, or something else along those lines anywhere else. That isn't to say that JSON is right every where, but I think it is more frequently the correct choice than XML is. ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

I find that JSON can just as self documenting as XML if used reasonably. Reasonably often will mean heavy use of the associative structure so that fields are clearly labeled with their names. YAML might enforce this a bit more though. Also, it doesn't require a consistent newline scheme. Yes, if that is important YAML is probably better. ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

Additionally, the wikipedia article for Qemu says that qemu can just read these files directly.

On Fri, Feb 16, 2007 at 07:44:27PM -0600, John Griessen wrote: I heard from a professor that the concept of offering server machines loaded with gEDA and such was a dead issue because of VMware's market share and popularity for avoiding installation time, and just using huge areas of disks as tools. I suppose some people might have 5 or so disk images they use in order to avoid integrating it all and getting 5 tools/entertainment_programs that way. Is that a good guess? VMWare probably isn't so good for entertainment programs. It does pass through OpenGL acceleration to some extent though. Also, it is an easy way to test stuff against Ubuntu or different FC versions, without constantly rebooting. I would imagine that Xen would be good as well, but Xen isn't particularly easy to use, and I don't know how it deals with graphical stuff, as I said. Is VMware's emulation now THAT good, that the usual 2GHz+ hardware has no trouble with it? and they offer a freebie now? (If you get someone else's image) VMWare Server runs adequately fast on a 2.8ghz Xeon w/ 2 gigs of ram. At work the IT guy has that set up running something like 6 images. Ram allocations are a bit skimpy (web services have 32-128 megs each, desktop installs for testing stuff have 256 megs allocated). The other developer where I work constantly complains about the speed compared to his desktop, but every time I try to look into it, the laptop runnign linux in vmware beats the pants off the desktop for building software, or even running gedit, so I don't know what he is complaining about. How many images can run at once with Player? One. But, there is also a free Server. It runs lots of images (don't know the max), but it caps the resolution at 1024x768 and doesn't do full screen mode. Is that their marketing ploy? If you want real convenience, you need a VMware license? Previously we (me and the IT guy) had trouble getting networking working nicely with laptops without buying the Workstation product instead of Player. The IT guy says he has resolved that, but I don't know what the trick was. What the problem was that player supported bridge or loopback, but not both at once. With loopback, the VMWare machines can't talk to the outside world (except perhaps via setting up a proxy or routing system on the host I guess), but with bridging, VMWare can't talk to the host when disconnected from a network (like sitting on you lap in an airport without wireless). I don't know where Server sits in this mix. This trouble was discovered when trying to setup Linux on Windows for another developer who refused to remove windows from the laptop, and also refused to try colinux. -- Joshua D.

What can I do with a VMPlayer Image ... Assuming I have VMPlayer (which I don't) is the image just something to view? a starting point for a system? ... or what? VMWare Player (and Server) is gratis, but you are not at liberty with it. The image is a starting point for a virtual system. The image is basically just a disk image that VMWare will use to boot a virtual machine, which will have a virtual display that shows up in a window on your desktop, uses the virtual disk (specifically, the image file) via a virtual SCSI card, and talks to a virtual NIC (which can either be NAT'ed with your machines onboard network connection, or with a compatible desktop ethernet device, can pretend to be an entirely new NIC with it's own MAC). When VMWare first launched, the main usage of it was to run Windows on Linux, or Linux on Windows. Rather than emulate everything, VMWare runs the guest system natively, but traps the execution of priveledged code and emulates just those features, so it isn't anywhere near as slow as Bochs or Qemu. VMWare is thus x86 only.x What VMWare does very right is that it allows you to easily move virtual machines, in the form of images, from one machine to another. As far as I know, it is not possible to do this with Solaris Zones (although they say they are working on it), Parallels, VirtualPC, or Xen. So, if you have developed a web application with a lot of dependencies, instead of the end user having to spend hours trying to get everything installed, they can instead download a few hundred meg VMWare image, and boot the already configured web app server, answer a few questions, then get straight to using it in only a few minutes. Does that answer your question? In this case a VMWare image could be a useful alternative to a LiveCD, with the benefit that you can keep your regular desktop running at the same time as the Image, which you can't exactly do with a livecd. -- Joshua D.

They both compile, but the windrvr6.ko won't load for me saying: [ 514.004730] windrvr6: no version for struct_module found: kernel tainted.
